Description

TOOL FOR A FLUID CONNECTION ASSEMBLY

FIELD

[0001] The present disclosure relates to fluid connectors, and, more particularly, to tools for assembling and disassembling a fluid connection assembly.

BACKGROUND

[0002] Fluid connectors, fluid connections and fluid connection assemblies are integral components for many applications, and especially for automotive applications. Since an automotive system is made up of various components such as a radiator, transmission, and engine, fluid must be able to travel not only within each component but also between components. An example of fluid traveling between components is the transmission fluid traveling from the transmission to the transmission oil cooler in order to lower the temperature of the transmission fluid. Another example of fluid traveling between components is refrigeration lines, which may carry a refrigerant. A refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle, and can be hazardous. As such, it is essential that fluid connectors for refrigeration lines be properly secured so as not to allow the release of any refrigerant.

[0003] Fluid predominantly moves between components via flexible or rigid hoses which connect to each component by fluid connectors. Such fluid connectors typically include a retainer, retaining clip, retaining ring clip, or snap ring carried on or in the connector body which is adapted to snap behind a raised shoulder of a tube when the tube is fully inserted into the connector body. In some cases, a retaining or locking band is employed to further secure the tube within the connector body. However, often times it is difficult to secure the tube within the connector body and retainer without the use of a machine or multiple tools. Additionally, it is difficult to disassemble or disconnect the tube from the retainer and thus connector body without damaging the various components of the fluid connection assembly.

[0004] Thus, there has been a long-felt need for a tool that promotes ease of assembly and disassembly of a fluid connection assembly, while preserving the integrity of the components of the fluid connection assembly such that they can be reused. SUMMARY

[0005] According to aspects illustrated herein, there is provided a tool for connecting and/or disconnecting a fluid connection assembly, comprising a first end, a second end, a first section, a second section hingedly connected to the first section, a first radially inward facing surface arranged on at least one of the first section and the second section, a second radially inward facing surface arranged on at least one of the first section and the second section, the second radially inward facing surface arranged radially inward of the first radially inward facing surface, a first groove arranged in the first radially inward facing surface proximate the first end, and a first radially outward facing surface forming the second end.

[0006] In some embodiments, the tool further comprises a flange extending radially inward from the first radially inward facing surface. In some embodiments, the flange forms the first end. In some embodiments, the flange is arranged adjacent to the first groove. In some embodiments, the second radially inward facing surface is arranged adjacent to the first radially inward facing surface. In some embodiments, the second radially inward facing surface comprises a second groove, the second groove arranged at the second end. In some embodiments, the first radially outward facing surface is frusto-conical. In some embodiments, the tool further comprises a second radially outward facing surface arranged adjacent to and radially outward from the first radially outward facing surface. In some embodiments, the second radially outward facing surface comprises knurling. In some embodiments, the tool further comprises one or more tabs operatively arranged to rotatably displace the second section with respect to the first section.

[0007] According to aspects illustrated herein, there is provided a tool for connecting and/or disconnecting a fluid connection assembly, comprising a first end, a second end, a first section, a second section hingedly connected to the first section, a first radially inward facing surface arranged on at least one of the first section and the second section, a second radially inward facing surface arranged on at least one of the first section and the second section, the second radially inward facing surface arranged radially inward of the first radially inward facing surface, a first groove arranged in the first radially inward facing surface proximate the first end, and a first radially outward facing surface forming the second end, the first radially outward facing surface being frusto-conical. [0008] In some embodiments, the tool further comprises a flange extending radially inward from the first radially inward facing surface. In some embodiments, the flange is arranged adjacent to the first end and the first groove. In some embodiments, the second radially inward facing surface is arranged adjacent to the first radially inward facing surface. In some embodiments, the second radially inward facing surface comprises a second groove, the second groove axially aligned with the second end. In some embodiments, the tool further comprises a second radially outward facing surface arranged adjacent to and radially outward from the first radially outward facing surface. In some embodiments, the second radially outward facing surface comprises knurling. In some embodiments, the tool further comprises one or more tabs operatively arranged to rotatably displace the second section with respect to the first section. In some embodiments, the tool further comprises a first hinge portion connected to one of the first section and the second section, the first hinge portion including at least one rod, and a second hinge portion connected to the other of the first section and the second section, the second hinge portion including at least one hole engaged with the at least one rod.

[0009] According to aspects illustrated herein, there is provided a tool for connecting and/or disconnecting a fluid connection assembly, comprising a first end, a second end, and a first section and a second section rotatably connected to the first section, wherein each of the first section and second section comprises a first radially inward facing surface, a second radially inward facing surface arranged radially inward of the first radially inward facing surface, a groove arranged in the first radially inward facing surface proximate the first end, and a radially outward facing surface forming the second end, the radially outward facing surface being frusto-conical. [0010] The present disclosure provides a fluid connection tool that provides easy removal of a tube or fluid line from a connector body and also provides a securing method to engage a locking band of a retainer for securing a tube in the connector body.

[0011] In some embodiments, the fluid connection tool comprises a first section and a second section that are hingedly connected via, for example, a hinge, living hinge, or hinge The tool comprises radially inward facing surfaces that include channels. The channels, when the tool is in a closed state, grip the locking band of a connector body allowing a user to engage and displace the collar to lock a tube in, or unlock a tube from, a connector body. In some embodiments, the two sections are squeezed together to compress fingers of the retainer prior to engaging and displacing the collar. The fluid connection tool further comprises another pair of radially arranged distal channels arranged on a radially inward facing surface of a frusto-conical end piece. The fluid connection tool is arranged to be inverted and closed around a section of the tube. Channels are arranged to engage a stepped surface of the tube, and the frusto-conical end piece is arranged to displace the fingers of the retainer radially outward to remove the tube from the connector body.

[0012] In some embodiments, the fluid connection tool comprises a first radially arranged channel arranged to engage and “trap” the locking band when fluid connection tool is in a closed position. The locking band may be frictionally secured to the distal end of the fingers of the retainer, or trapped or secured between two barbs on the distal ends of the fingers. When locking band is arranged at the distal end of the fingers, the tube is locked within the connector body. When the two sections or halves of fluid connection tool are squeezed together, protrusions on the tool engage the fingers and compress them thereby allowing channels of the tool to engage and displace the locking band to a distal end of the fingers (i.e., the locked state) or to the proximal end of the fingers (i.e., the unlocked state).

[0013] In some embodiments, the fluid connection tool engages the tube in order to remove it from the retainer and connector body. In order to use the fluid connection tool to remove an engaged tube, it is first inverted such that the frusto-conical section faces toward the connector body and positioned in a closed state. The fluid connection tool is then slid radially between the fingers and the tube member. A user then will squeeze the two sections of the fluid connection tool together to frictionally grab the tube within distal channels and radially inward facing surfaces of the tool and pull the tube member to release and remove the tube member from the connector body. In some embodiments, the frusto-conical section displaces the fingers of the retainer radially outward and the tube and the tool are pulled out of the connector body (i.e., if no frictional engagement occurs).

[0014] In some embodiments, in a first configuration for displacing the locking band with respect to the retainer, the two halves of the tool are closed around the fingers with the knurled side toward the connector body. The protrusions of the tool, when closed, include a smaller diameter and should be arranged just below the locking band. The halves are squeezed together to compress the fingers (i.e., displace the fingers radially inward). The tool is then displaced either toward the connector body dragging the locking band below the lower barb to the unlocked state (the tool can now be removed and the band can be easily pushed down all the way), or away from the connector body dragging the locking band above the lower bard to the locked state. In a second configuration for removing the tube from the retainer, the tool is inverted such that the frusto- conical end is directed toward the connector body. The tool is in the closed state (i.e., the halves abut or are arranged proximate each other) but allowed to slide along the tube. The tool is slid down the tube to engage the frusto-conical section with the fingers (forcing them radially outward and out of engagement with the tube shoulder) until the shoulder of the tool is arranged proximate the distal end of the fingers. The halves of the tool are squeezed together to “grab” the tube and the tube is pulled out of the retainer and connector body.

It should further be appreciated that the term “tube” can mean a rigid or flexible conduit of any material suitable for containing and allowing the flow of a gas or a liquid.

[0033] Adverting now to the figures, Figure 1 A is a perspective view of fluid connection assembly 10, in an unlocked state. Figure IB is a perspective view of fluid connection assembly 10 shown in Figure 1A, in a locked state. Figure 2 is an exploded perspective view of fluid connection assembly 10. Fluid connection assembly 10 generally comprises connector body 40, tube or tube or hose 80, and retainer 100. The following description should be read in view of Figures 1A-2.

[0034] Tube 80 comprises end 82, section 83, shoulder 87, section 89, end 94, and through- bore 96. Through-bore 96 extends through tube 80 from end 82 to end 94. Section 83 is arranged between end 82 and shoulder 87 and comprises radially outward facing surface 84. Radially outward facing surface 84 includes a substantially constant diameter. In some embodiments, radially outward facing surface 84 comprises a frusto-conical taper proximate end 82 (see Figures 4A-B). In some embodiments, section 83 further comprises a raised section, namely, radially outward facing surface 85, arranged between radially outward facing surface 84 and shoulder 87. Radially outward facing surface 85 has a diameter that is greater than the diameter of radially outward facing surface 84. Radially outward facing surface 85 is connected to radially outward facing surface 84 via surface 85A. In some embodiments, surface 85A is an axial surface facing axial direction ADI. Shoulder 87 is arranged between section 83 and section 89 and comprises radially outward facing surface 86 and surface 88. As shown, radially outward facing surface 86 is a frusto-conical surface extending from radially outward surface 84 to surface 88. Radially outward facing surface 86 increases in diameter is axial direction AD2. In some embodiments, radially outward facing surface 86 is an axial surface facing at least partially in axial direction ADI. In some embodiments, tube 80 comprises a constant diameter radially outward facing surface arranged between radially outward facing surface 86 and surface 88. Shoulder surface 88 is an axial surface facing at least partially in axial direction AD2. Section 89 is arranged between shoulder 87 and end 94 and comprises radially outward facing surface 92. Radially outward facing surface 92 includes a substantially constant diameter. In some embodiments, section 89 further comprises a raised section, namely, radially outward facing surface 90, arranged between shoulder surface 88 and radially outward facing surface 92. Radially outward facing surface 90 has a diameter that is greater than the diameter of radially outward facing surface 92. Tube 80 is arranged to be inserted, specifically with end 82 first, into connector body 40 and retainer 100. Tube 80 is inserted into connector body 40 and retainer 100 until fingers 110 and 120 snap over shoulder 87. It is the engagement of the projections of fingers 110 and 120 with shoulder surface 88 that secures tube 80 within connector body 40. It should be appreciated that tube 80 may be any traditional tube comprising a bead, radially outward extending protrusion or flange, or ramp profile, which extends radially outward and axially on the outer surface of the tube, to displace the fingers of a retainer and secure the tube within the connector body. In some embodiments, tube 80 comprises a metal. In some embodiments, tube 80 comprises a nonmetal (e.g., polymer, rubber, ceramic, etc.).

[0035] Figure 3A is a perspective view of retainer 100. Figure 3B is an elevational view of retainer 100. The following description should be read in view of Figures 1A-3B.

[0036] Retainer 100 generally comprises ring portion 106 forming end 102 and a plurality fingers (e.g., fingers 110 and fingers 120) extending from ring portion 106 and forming end 104. Ring portion 106 is generally ring shaped and comprises through-bore 101. In some embodiments, when retainer 100 is fully inserted into connector body 40, end 102 is operatively arranged to create the second half of the seal or O-ring gland (i.e., for groove 50).

[0037] Fingers 110 extend from ring portion 106 in axial direction AD2 and are operatively arranged to engage shoulder 87 of tube 80 and locking band 20. Each of fingers 110 comprises radially outward extending projection 112 and radially inward extending projection 114. Projections 112 extend in radial direction RD1 and are operatively arranged to engage locking band 20. Specifically, when in the locked state, projections 112 prevent locking band 20 from being displaced in axial direction ADI, as will be described in greater detail below. In some embodiments, projections 112 are arranged at a location between end 104 and locking ring 106. Projections 114 extend in radial direction RD2 and, when engaged with shoulder 87, lock tube 80 in retainer 100 (and connector body 40). Projections 114 form surfaces 116. In some embodiments, surfaces 116 are frusto-conical surfaces. As tube 80 is inserted into retainer 100 in axial direction ADI, frusto-conical surfaces 116 engage radially outward facing surface 86 of shoulder 87 forcing fingers 110 radially outward (i.e., in radial direction RD1). Once projections 114 are aligned with section 89 (i.e., once projections 114 axially pass shoulder 87), fingers 110 snap back radially inward (i.e., in radial direction RD2) and secure tube 80 within retainer 100. Fingers 110 are elastic and are operatively arranged to flex and/or bend relative to ring portion 106. In some embodiments, retainer 100 comprises a polymer. In some embodiments, fingers 110 comprise a recess or thinned out portion that allows greater flexion (i.e., arranged axially between projections 114 and ring portion 106). In some embodiments, fingers 110 are arranged such that the radially outward facing surface is frusto-conical (i.e., the radially outward facing surface increases in diameter in axial direction AD2).

[0038] Fingers 120 extend from ring portion 106 in axial direction AD2 and are operatively arranged to engage shoulder 87 of tube 80 and locking band 20. Each of fingers 120 comprises radially outward extending projection 122 and radially inward extending projection 124. Projections 122 extend in radial direction RD1 and are operatively arranged to engage locking band 20. Specifically, when in the locked state, projections 122 prevent locking band 20 from being displaced in axial direction AD2, as will be described in greater detail below. In some embodiments, projections 122 are arranged at end 104. Projections 124 extend in radial direction RD2 and, when engaged with shoulder 87, lock tube 80 in retainer 100 (and connector body 40). Projections 124 form surface 126. In some embodiments, surfaces 126 are frusto-conical surfaces. As tube 80 is inserted into retainer 100 in axial direction ADI, frusto-conical surfaces 126 engage radially outward facing surface 86 of shoulder 87 forcing fingers 120 radially outward (i.e., in radial direction RD1). Once projections 124 are aligned with section 89 (i.e., once projections 124 axially pass shoulder 87), fingers 120 snap back radially inward (i.e., in radial direction RD2) and secure tube 80 within retainer 100. Fingers 120 are elastic and are operatively arranged to flex and/or bend relative to ring portion 106. In some embodiments, fingers 120 comprise a recess or thinned out portion that allows greater flexion (i.e., arranged axially between projections 124 and ring portion 106). In some embodiments, retainer 100 further comprises apertures 130 arranged radially outward of fingers 110 and/or fingers 120. Apertures 130 extend at least partially through ring portion 106 and may aid in increasing the overall flexion of fingers 110 and 120. Apertures 130 also aid in the molding process of retainer 100. In some embodiments, fingers 120 are arranged such that the radially outward facing surface is frusto-conical (i.e., the radially outward facing surface increases in diameter in axial direction AD2).

[0039] In some embodiments, and as shown, fingers 110 and fingers 120 alternate circumferentially. In some embodiments, fingers 110 and fingers 120 do not alternate every single finger. For example, in a circumferential direction, two fingers 110 are adjacently arranged followed by two fingers 120 adjacently arranged. In another example, two fingers 110 are adjacently arranged, followed by one finger 120, followed by two fingers 110 adjacently arranged. It should be further appreciated that while projections 112 and 122 are arranged on adjacently formed fingers 110 and 120, respectively, in some embodiments, projections 112 and 122 are arranged on the same finger so as to limit movement of locking band 20 in the locked state of fluid connection assembly. In some embodiments, retainer 100 comprises a polymer.

[0040] Locking band 20 is generally arranged around retainer 100, specifically, fingers 110 and 120. Locking band 20 is operatively arranged to be displaced in axial directions AD2 and ADI with respect to ring portion 106 to lock and unlock fluid connection assembly 10. Additionally, locking band 20 is arranged to engage projections 112 and 122 of fingers 110 and 120, respectively, as will be described in greater detail below. In some embodiments, locking band 20 comprises a metal (e.g., steel, aluminum, etc.). In some embodiments, locking band 20 comprises a nonmetal (e.g., polymer, vinyl, etc.).

[0041] Figure 4A is a cross-sectional view of fluid connection assembly 10 taken generally along line 4A-4A in Figure 1 A. Figure 4B is a cross-sectional view of fluid connection assembly 10 taken generally along line 4B-4B in Figure 1A. The following description should be read in view of Figures 1A-4A.

[0042] Connector body 40 comprises through-bore 41 extending from end 42 to end 44, radially inward facing surface 46, radially inward facing surface 48, flange 54, head 58, and radially outward facing surface 60. Connector body 40 is arranged to be connected to a component that is filled with a fluid. For example, connector body 40 may be connected to a refrigeration compressor via radially outward facing surface 60, which may comprise external threading. Connector body 40 may be screwed into a threaded hole in the compressor via head 58 (e.g., using a wrench), which is then filled with refrigerant fluid. In some embodiments, head 58 is hexagonal; however, it should be appreciated that head 58 may comprise any geometry suitable for applying torque to connector body 40. Another component in which fluid connector 10, specifically connector body 40, may be installed into is a condenser, evaporator, or pump. It should be appreciated that fluid connector 10 may be used in various other components, assemblies, and subassemblies in which fluid connection is desired. Radially outward facing surface 60 may further comprise groove 64. A seal or O-ring may be arranged in groove 64 to create a fluid tight seal between connector body 40 and the component it is connected to. Seal 30 and/or seal 32 are arranged in connector body 40. Specifically, seal 30 is arranged in groove 50 and seal 32 is arranged in groove 52. Grooves 50 and 52 are arranged in radially outward facing surface 48. In some embodiments, seal 30 and seal 32 are O-rings. Connector body 40 further comprises surface 47, which extends between and connects radially inward facing surface 46 and radially inward facing surface 48. Surface 47 is operatively arranged to engage retainer 100, as will be described in greater detail below. Flange 54 extends from head 58 in axial direction AD2. Flange 54 is operatively arranged to be crimped around retainer 100 (i.e., in radially direction RD2), specifically ring portion 106, to secure retainer 100 to connector body 40. Flange 54 is shown crimped in Figures 1 A-B and 4A-B, and uncrimped in Figure 2. In some embodiments, connector body 40 comprises a metal. In some embodiments, connector body 40 comprises a conductive material with flange 54 comprising a suitable malleable material.

[0043] To assembly fluid connection assembly 10, retainer 100 is inserted in axial direction ADI, with end 102 first, into connector body 40. As shown in Figures 4A-B, end 102 of retainer 100 engages surface 47 of connector body 40. Flange 54 is then crimped radially inward (i.e., in radial direction RD2), around ring portion 106, to secure retainer 100 within connector body 40. In the secured state, retainer 100 is prevented from displacement in axial direction ADI by surface 47 and axial direction AD2 by crimped flange 54. It should be appreciated that tube 80 generally is not inserted into retainer 100 until flange 54 has been crimped. Then tube 80 is inserted in axial direction ADI, with end 82 first, into retainer 100. As tube 80 is inserted into retainer 100, frusto- conical surfaces 116 of projections 114 and frusto-conical surfaces 126 of projections 124 engage shoulder 87 displacing fingers 110 and fingers 120 radially outward, in radial direction RD1, respectively. Once projections 114 and projections 124 are aligned with section 89, fingers 110 and fingers 120 snap back radially inward, in radial direction RD2, and projections 114 and projections 124 engage shoulder 87 and shoulder surface 88, thereby securing tube 80 in retainer 100

[0044] Once tube 80 is fully engaged in retainer 100, locking band 20 is displaced from the unlocked position (Figure 4A) in axial direction AD2 to the locked position (Figure 4B). Locking band 20 slides over projection 112 in axial direction AD2 due to the ramp surface arranged on projection 112. Once locking band 20 passes projection 112 in axial direction AD2, the axial surface of projection 112 prevents displacement of locking band 20 in axial direction ADI. Additionally, the axial surface of projection 122 prevents locking band 20 from displacing any further in axial direction AD2. Thus, in the locked state shown in Figures IB and 4B, locking band 20 engages projections 112 and 122 and is prevented thereby from displacing axially, which secures fluid connection assembly in the locked state.

[0045] It should be appreciated that, when retainer 100 is fully assembled to connector body 40, fingers 110 and fingers 120 extend out of, in axial direction AD2, connector body 40. Thus, when tube 80 is subsequently inserted into retainer 100, protrusions 114 of fingers 110 and protrusions 124 of fingers 120 engage shoulder 87 outside of connector body 40, rather than inside. This is advantageous because it allows for greater flexion of fingers 110 and fingers 120 and thus a lower required insertion force of tube 80 into retainer 100 (and connector body 40).

[0046] In some embodiments, and as shown in Figures 4A-B, in the fully assembled state surface 85 A is arranged proximate to or abuts against surface 47. Thus, the engagement of surface 47 and surface 85A prevents displacement of tube 80 with respect to connector body 40 in axial direction ADI, and the engagement of projections 114 and 116 with shoulder 87 prevents displacement of tube 80 with respect to connector body 40 in axial direction AD2.

[0047] Figure 5A is a perspective view of tool 200 for fluid connection assembly 10, in a closed state. Figure 5B is a perspective view of tool 200, in an open state. Figure 6 is an exploded perspective view of tool 200. Tool or fluid connection tool 200 generally comprises section 210A and section 210B. Section 210B is hingedly connected to section 210A and, in a closed state as shown in Figure 5A, sections 210A and 210B form hole 202. The following description should be read in view of Figures 5A-6.

[0048] Section 210A comprises end 212A, end 214A, radially inward facing surface 218A, radially inward facing surface 224A, radially outward facing surface 228A, and radially outward facing surface 230A. Section 210A further comprises surface 216A operatively arranged to abut against or be in close proximity to surface 216B, as will be described in greater detail below. Radially inward facing surface 218A generally extends from end 212A to radially inward facing surface 224A. In some embodiments, and as shown, radially inward facing surface 218A is connected to radially inward facing surface 224A via an axial surface. Radially inward facing surface 218A generally comprises groove 220A and flange 222A. In some embodiments, radially inward facing surface 218A comprises a constant diameter. In some embodiments, radially inward facing surface 218A comprises a variable diameter.

[0049] Groove 220A extends radially outward from radially inward facing surface 218A and is operatively arranged to engage locking band 20, as will be described in greater detail below. Thus, the diameter of groove 220A is greater than the diameter of radially inward facing surface 218A. Groove 220A is arranged proximate end 212A. In some embodiments, and as shown, groove 220A forms two axial surfaces within section 210A (i.e., formed on either side of groove 220A). In some embodiments, groove 220A comprises a constant diameter. In some embodiments, groove 220A comprises a variable diameter.

[0050] Flange 222A extends radially inward from radially inward facing surface 218A and is operatively arranged to engage fingers 110 and fingers 120 at their proximate ends (i.e., nearer end 102), as will be described in greater detail below. Thus, the diameter of flange 222A is less than the diameter of radially inward facing surface 218A. In some embodiments, and as shown, flange 222A is connected to and forms end 212A and an axial surface (on the side opposite that of end 212A). In some embodiments, flange 222A comprises a constant diameter. In some embodiments, flange 222A comprises a variable diameter. Radially inward facing surface 218A, groove 220A, flange 222A, and end 212A are all connected to surface 216A.

[0051] Radially inward facing surface 224A extends from radially inward facing surface 218A to end 214A. Radially inward facing surface 224A generally comprises groove 226A. Radially inward facing surface 224A is arranged to engage and/or abut against radially outward facing surface 92 of tube 80, as will be described in greater detail below. In some embodiments, radially inward facing surface 224A is arranged to frictionally engage radially outward facing surface 92 such that tool 200 and tube 80 are fixedly secured (i.e., when section 210A and section 210B are compressed together with enough force). In some embodiments, radially inward facing surface 224A comprises a constant diameter. In some embodiments, radially inward facing surface 224A comprises a variable diameter.

[0052] Groove 226A extends radially outward from radially inward facing surface 224A and is operatively arranged to engage radially outward facing surface 90 of tube 80. Thus, the diameter of groove 226A is greater than the diameter of radially inward facing surface 224A. In some embodiments, and as shown, groove 226A is connected to and forms end 214A. In some embodiments, groove 226A comprises a constant diameter. In some embodiments, groove 226A comprises a variable diameter. Radially inward facing surface 224A, groove 226A, and end 214A are all connected to surface 216A.

[0053] Radially outward facing surface 228A is connected to and forms end 212A, and extends from end 212A to radially outward facing surface 230A. In some embodiments, and as shown, radially outward facing surface 228A is connected to radially outward facing surface 230A via an axial surface. In some embodiments, radially outward facing surface 228A comprises knurling, or small ridges or beads thereon to aid in gripping. In some embodiments, radially outward facing surface 228A comprises a constant diameter. In some embodiments, radially outward facing surface 228A comprises a variable diameter.

[0054] Radially outward facing surface 230A is connected to and forms end 214A, and extends from radially outward facing surface 228A to end 214A. Radially outward facing surface 230A is frusto-conical and is operatively arranged to engage fingers 110 and fingers 120. Specifically, radially outward facing surface 230A is arranged to be positioned between radially outward facing surface 92 and surfaces 116 and 126 in order to displace fingers 110 and fingers 120 radially outward, respectively, thereby disengaging fingers 110 and fingers 120 from shoulder 87, as will be described in greater detail below. Radially outward facing surface 228A and radially outward facing surface 230A are both connected to surface 216A.

[0055] Section 210A further comprises hinge portion 240A and tab 244A. Hinge portion 240A is operatively arranged to engage hinge portion 240B to rotatably connect section 210A to section 210B. In some embodiments, and as shown, hinge portion 240A is fixedly secured to radially outward facing surface 228A and comprises at least one axially arranged rod 242A. Tab 244A is fixedly connected to hinge portion 240A and/or radially outward facing surface 228A. Tab 244A is arranged to work together with tab 244B of section 210B to open and close tool 200. [0056] Section 210B is substantially similar to section 210A and comprises end 212B, end 214B, radially inward facing surface 218B, radially inward facing surface 224B, radially outward facing surface 228B, and radially outward facing surface 230B. Section 210B further comprises surface 216B operatively arranged to abut against or be in close proximity to surface 216A, as will be described in greater detail below. Radially inward facing surface 218B generally extends from end 212B to radially inward facing surface 224B. In some embodiments, and as shown, radially inward facing surface 218B is connected to radially inward facing surface 224B via an axial surface. Radially inward facing surface 218B generally comprises groove 220B and flange 222B. In some embodiments, radially inward facing surface 218B comprises a constant diameter. In some embodiments, radially inward facing surface 218B comprises a variable diameter.

[0057] Groove 220B extends radially outward from radially inward facing surface 218B and is operatively arranged to engage locking band 20, as will be described in greater detail below. Thus, the diameter of groove 220B is greater than the diameter of radially inward facing surface 218B. Groove 220B is arranged proximate end 212B. In some embodiments, and as shown, groove 220B forms two axial surfaces within section 210B (i.e., formed on either side of groove 220B). In some embodiments, groove 220B comprises a constant diameter. In some embodiments, groove 220B comprises a variable diameter.

[0058] Flange 222B extends radially inward from radially inward facing surface 218B and is operatively arranged to engage fingers 110 and fingers 120 at their proximate ends (i.e., nearer end 102), as will be described in greater detail below. Thus, the diameter of flange 222B is less than the diameter of radially inward facing surface 218B. In some embodiments, and as shown, flange 222B is connected to and forms end 212B and an axial surface (on the side opposite that of end 212B). In some embodiments, flange 222B comprises a constant diameter. In some embodiments, flange 222B comprises a variable diameter. Radially inward facing surface 218B, groove 220B, flange 222B, and end 212B are all connected to surface 216B. [0059] Radially inward facing surface 224B extends from radially inward facing surface

218B to end 214B. Radially inward facing surface 224B generally comprises groove 226B. Radially inward facing surface 224B is arranged to engage and/or abut against radially outward facing surface 92 of tube 80, as will be described in greater detail below. In some embodiments, radially inward facing surface 224B is arranged to frictionally engage radially outward facing surface 92 such that tool 200 and tube 80 are fixedly secured (i.e., when section 210A and section 210B are compressed together with enough force). In some embodiments, radially inward facing surface 224B comprises a constant diameter. In some embodiments, radially inward facing surface 224B comprises a variable diameter.

[0060] Groove 226B extends radially outward from radially inward facing surface 224B and is operatively arranged to engage radially outward facing surface 90 of tube 80. Thus, the diameter of groove 226B is greater than the diameter of radially inward facing surface 224B. In some embodiments, and as shown, groove 226B is connected to and forms end 214B. In some embodiments, groove 226B comprises a constant diameter. In some embodiments, groove 226B comprises a variable diameter. Radially inward facing surface 224B, groove 226B, and end 214B are all connected to surface 216B.

[0061] Radially outward facing surface 228B is connected to and forms end 212B, and extends from end 212B to radially outward facing surface 230B. In some embodiments, and as shown, radially outward facing surface 228B is connected to radially outward facing surface 230B via an axial surface. In some embodiments, radially outward facing surface 228B comprises knurling. In some embodiments, radially outward facing surface 228B comprises a constant diameter. In some embodiments, radially outward facing surface 228B comprises a variable diameter.

[0062] Radially outward facing surface 230B is connected to and forms end 214B, and extends from radially outward facing surface 228B to end 214B. Radially outward facing surface 230B is frusto-conical and is operatively arranged to engage fingers 110 and fingers 120. Specifically, radially outward facing surface 230B is arranged to be positioned between radially outward facing surface 92 and surfaces 116 and 126 in order to displace fingers 110 and fingers 120 radially outward, respectively, thereby disengaging fingers 110 and fingers 120 from shoulder 87, as will be described in greater detail below. Radially outward facing surface 228B and radially outward facing surface 230B are both connected to surface 216B.

[0063] Section 210B further comprises hinge portion 240B and tab 244B. Hinge portion 240B is operatively arranged to engage hinge portion 240A to rotatably connect section 210B to section 210A. In some embodiments, and as shown, hinge portion 240B is fixedly secured to radially outward facing surface 228B and comprises at least one hole 242B. Holes 242B are arranged to engage rods 242A, similar to a hinge, to pivotably connect sections 210A and 210B. In some embodiments, sections 210A and 210B are connected via a living hinge, or any other element suitable to pivotably or rotatably sections 210A and 210B. Tab 244B is fixedly connected to hinge portion 240B and/or radially outward facing surface 228B. Tab 244B is arranged to work together with tab 244A of section 210A to open and close tool 200. In some embodiments, tool 200 further comprises a spring that works in conjunction with hinge portions 240A-B to maintain tool 200 in the closed position (as shown in Figure 5A). In some embodiments, tool 200 further comprises a spring that works in conjunction with hinge portions 240A-B to maintain tool 200 in the open position (as shown in Figure 5B). It should be appreciated that in the closed position, surface 216A abuts against or is arranged immediately proximate to surface 216B.

[0064] It should be appreciated that radially inward facing surfaces 218A-B are equal in diameter, grooves 220A-B are equal in diameter, flanges 222A-B are equal in diameter, radially inward facing surfaces 224A-B are equal in diameter, grooves 226A-B are equal in diameter, radially outward facing surfaces 228A-B are equal in diameter, and radially outward facing surfaces 230A-B are equal in diameter. When tool 200 is in the closed state, as shown in Figure 5A, radially inward facing surfaces 218A-B are aligned, grooves 220A-B are aligned, flanges 222A-B are aligned, radially inward facing surfaces 224A-B are aligned, grooves 226A-B are aligned, radially outward facing surfaces 228A-B are aligned, and radially outward facing surfaces 230A-B are aligned.

[0065] Figure 7A a perspective view of tool 200 engaged with fluid connection assembly 10, in a first configuration, wherein fluid connection assembly 10 is in a locked state. In the locked state of fluid connection assembly 10, locking band 20 is arranged at the distal end of the fingers of retainer 100. Specifically, and as previously described, in some embodiments locking band 20 is arranged between projections on the outer surfaces of the fingers. Tool 200 is positioned such that grooves 220A-B are aligned with and/or engage locking band 20, and flanges 222A-B are aligned with and/or engage the proximate end of the fingers of retainer 100. To disengage locking band 20 from the projections (i.e., unlock fluid connection assembly 10), section 210A and section 210B are squeezed together about the hinge. Flanges 222A-B force the fingers of retainer 100 radially inward thereby disengaging the projections from the locking band. Then tool 200 is displaced in axial direction ADI with respect to connector body 40.

[0066] To engage locking band 20 with the projections (i.e., to lock fluid connection assembly 10), tool 200 is positioned such that grooves 220A-B are aligned with and/or engage locking band 20, and flanges 222A-B are aligned with and/or engage the proximate end of the fingers of retainer 100. Section 210A and section 210B are squeezed together about the hinge. Flanges 222A-B force the fingers of retainer 100 radially inward and tool 200 is displaced in axial direction AD2 with respect to connector body 40 until locking band 20 is arranged axially between the proximal and distal projections.

[0067] Figure 7B a perspective view of tool 200 engaged with fluid connection assembly 10, in the first configuration, wherein fluid connection assembly 10 is in an unlocked state. Once locking band 20 is displaced (in axial direction ADI) to a position below the projections of the fingers (i.e., a position axially between the proximate projection and flange 54), the force applied to tool 200 may then be released. Sections 210A and 210B may be displaced away from each other using tabs 244A-B and the tool removed from fluid connection assembly 10. At that point, a user can manually displace locking band 20 in axial direction ADI even further toward flange 54.

[0068] Figure 8 is a perspective view of tool 200 engaged with fluid connection assembly 10, in a second configuration. Figure 9 is a cross-sectional view of tool 200 engaged with the fluid connection assembly 10 taken generally along line 9-9 in Figure 8. Once locking band 20 is in the unlocked position, as shown in Figures 8-9, tool 200 is inverted and ends 214A-B are directed toward connector body 40 (ends 212A-B are directed away from connector body 40). Tool 200 is positioned such that radially inward facing surfaces 224A-B engage and/or abut radially outward facing surface 92 of tube 80. Then tool 200 is slid or displaced along tube 80 in axial direction ADI with respect thereto until grooves 226A-B engage radially outward facing surface 90 and frusto-conical radially outward facing surfaces 230A-B engage inward facing surfaces of the fingers of retainer 100. Radially outward facing surfaces 230A-B displace the fingers radially outward thereby disengaging them from shoulder 87, and specifically shoulder surface 88. Then, tube 80, and tool 200, can be displaced in axial direction AD2 with respect to connector body 40 and retainer 100. In some embodiments, sections 210A and 210B are squeezed together thereby fixedly securing tool 200 to tube 80, and tool 200 can be displaced in axial direction AD2 with respect to connector body 40 and retainer 100, which also removes tube 80 therefrom.

[0069] It will be appreciated that various aspects of the disclosure above and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. Various presently unforeseen or unanticipated alternatives, modifications, variations, or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
