The clip 30 has a snap-fit portion 32 and

projections

34, 36. The

projections

34, 36 are connected to the latch 32. The protruding

portions

34 and 36 are disposed on the fastening portion 32, and the protruding

portions

34 and 36 protrude from the fastening portion 32.

The fastening portion 32 is snappingly received in the fastening groove 222, so as to fasten the fastening member 30 to the pipe joint 20. The

protrusions

34, 36, thereby preventing the pipe joint 20 from being separated from the accommodating portion.

The protruding

portions

34 and 36 of the clip member 30 can be inserted into the insertion holes 18 and 19, so that the limiting

portions

18 and 19 can limit the protruding

portions

34 and 36. The

protrusions

34, 36 of the clip 30 are separated from the insertion holes 18, 19, the position of the limiting

portions

18, 19 on the

protrusions

34, 36 is lost, and at this time, the pipe joint 20 can be separated from the accommodating portion, so that the pipe joint 20 can be detached from the housing 10. The assembly is convenient, and the installation process is simple.

Further, the pipe joint 20 has an axial direction, and in the axial direction of the pipe joint 20, the fastening portion 32 is accommodated in the fastening groove 222 in a fastening manner, so that the limiting

portions

18 and 19 are axially fixed with the pipe joint 20. The

stop portions

18, 19 cannot move axially relative to the pipe joint 20.

In the axial direction of the pipe joint 20, the

stopper portions

18, 19 axially restrict the projecting

portions

34, 36, thereby axially restricting the

stopper portions

18, 19 and the pipe joint 20 axially fixed together, and preventing the pipe joint 20 from axially coming out of the accommodating portion, thereby preventing the pipe joint 20 from axially separating from the housing 10.

The specific structure of the housing 10 can be set as required, and referring to fig. 6 to 10, the position-limiting

portions

18 and 19 and the protruding

portions

34 and 36 can be set correspondingly. In this embodiment, the housing 10 includes a first shell 12 and a second shell 14, and the second shell 14 is covered and connected to the second shell 14. The accommodating portion is an accommodating hole 16 defined by the first shell 12 and the second shell 14. The receiving hole 16 is adapted to the shape of the pipe connector 20.

For circumferential positioning, in the circumferential direction of the accommodating hole 16, the insertion holes 18 and 19 can circumferentially limit the

protrusions

34 and 36 to prevent the snap-in member 30 from circumferentially rotating relative to the accommodating hole 16. Thus, in the circumferential direction and the axial direction of the accommodating hole 16, the clamping piece 30 is fixedly arranged, so that the clamping action between the clamping piece 30 and the clamping groove 222 and the limiting action between the clamping piece 30 and the

jacks

18 and 19 are prevented from being influenced.

In order to form the accommodating hole 16, a first accommodating groove 122 is formed on the first shell 12, and a second accommodating groove 142 is formed on the second shell 14. When the pipe joint 20 is installed in the first receiving groove 122, the first protruding portion 34 is inserted into the first insertion hole 18. When the second shell 14 is covered on the first shell 12, the second protruding portion 36 is inserted into the second insertion hole 19, and the second receiving groove 142 and the first receiving groove 122 together enclose the receiving hole. The assembly is convenient, and the installation process is simple.

In the axial direction of the receiving bore 16, the step 124 axially limits the pipe connection 20. When the pipe joint 20 is installed in the receiving hole, the step 124 axially limits the pipe joint 20, so that the pipe joint 20 can be stopped, the installation position is accurate, and the assembly is convenient.

The structure of the locking groove 222 can be specifically configured as required, as long as the locking portion 32 can be locked in the locking groove 222 to achieve the limiting.

In an alternative example, as shown in the figure, the locking groove 222 is provided on the outer circumferential surface of the pipe joint 20. The locking groove 222 extends in the circumferential direction of the pipe joint 20. The locking portion 32 is accommodated in at least a portion of the locking slot 222. In this way, the engagement portion 32 can be reliably axially fixed to the pipe joint 20 in the axial direction of the pipe joint 20.

In this example, the clip 30 may be provided as a steel wire, as shown in the drawings. For example, the cross-section of the steel wire may be provided as a circle. The snap-in portion 32 comprises one or more arcuate segments. When the locking portion 32 is received in the locking groove 222, the protruding

portions

34, 36 protrude from the outer surface of the pipe joint 20 and extend a predetermined distance.

In this example, the

projections

34, 36 may include two first projections 34. The two first protrusions 34 protrude from the outer surface of the pipe joint 20 from both ends of the clamping member 30 to be inserted into the first insertion holes 18.

The first projection 34 may be provided as a straight line segment. The first protrusion 34 is connected to an end of the locking portion 32. The first projection 34 is arranged tangentially to the arc segment.

The two first protrusions 34 may be provided as straight line segments parallel to each other.

Furthermore, the projections can also be provided in other numbers, for example one or at least three.

projections

34, 36 include at least one second projection 36. Two adjacent arc segments are connected by the second protrusion 36. The second protrusion 36 protrudes from the outer surface of the pipe joint 20 to be inserted into the second insertion hole 19. For example, the second protrusion 36 has a U shape, a V shape, a W shape, or an arc shape; both ends of the second protruding portion 36 may be connected to two adjacent arc-shaped segments, respectively.

In this example, the clamping member 30 can pass through the clamping groove 222 along the radial direction of the pipe joint 20, so that the arc-shaped segment is received in the clamping groove 222, and the protruding

parts

34 and 36 protrude out of the outer surface of the pipe joint 20.

In this example, the steel wire may be bent in the longitudinal direction thereof, and the locking portion 32, the first protrusion 34, and the second protrusion 36 may be integrally formed.

The clamping piece 30 is arranged as a steel wire, and the steel wire is simple in structure and easy to process.
