  • the locking ring 5 presents in its unaffected state a diameter which is slightly larger than the diameter of the groove 4, and is also slightly resilient. Consequently, the locking ring 5 may be squeezed together and set free from engagement with the groove 10 of the coupling sleeve 9.
  • the coupling member 1 may now be drawn out of the coupling sleeve 9.
  • the coupling device may be disassembled by inserting a tool, for example a screwdriver, in the recess 7, and squeezing together the locking ring in the radial direc ⁇ tion. In this manner, the locking ring may be released from engagement with the groove 10 in the coupling sleeve 9.

  • the coupling members 1 are provided with ribbed tube connectors 12 for the connection of rubber hoses.
  • Each of the three coupling members 1 comprises circular grooves or notches which accomodate sealing rings 13.
  • the sealing rings 13, which may be manufactured from rubber or the like, prevent dirt and moisture from leaking into or out of the connector.
  • the coupling member 1 is provided with an essentially cylindrical section 2 and a second section 3.
  • the second section 3 is provided with a recess 8 in which an actuation element 14 is arranged.
  • the coupling member 1 is preferably also provided with a ribbed tube connector 12 for the connection of rubber hoses or the like.
  • the coupling sleeve 9 in which the coupling member 1 is intended to be inserted is provided with conical inner guiding surfaces 11, which facilitate the insertion of the coupling member 1.
  • the coupling sleeve 9 is also provided with a circular groove 10 which is intended to cooperate with a locking ring 5, in accordance with the above- mentioned description.
  • the coupling member 1 comprises a circular groove or notch which accomodates a sealing ring 15, which preferably is made from rubber or the like.
  • the sealing ring 15 is arranged around the coupling member 1 and extends over a section of the actuation element 14.
  • the actuation element 14 is movable in the axial direction of the coupling member 1 and comprises a first protruding section 16.
  • the actuation element 14 also comprises a second protruding section (not visible in Fig. 6).
  • the first protruding section 16 is be brought into contact with the sealing ring 15 if the actuation element 14 is pushed down (manually or by means of a tool), i.e. in a direction towards the sealing ring 15.
  • the protruding sections 16, 17 have greater width than the rest of the actuation element 14, which is essentially aligned with the circumference of notch which accomodates the sealing ring 15.
  • the locking ring 5 is arranged so that its prongs 6 extend on the rear side of the actuation element 14, i.e. between the actuation element 14 and the outer wall of the cylindrical section 2. The cooperation of the locking ring 5 and the actuation element 14 will be described in greater detail below.
  • Fig. 7 shows a perspective view of the actuation element 14, which is provided with the protruding section 16 and the second protruding section 17.
  • the protruding sections 16, 17 have greater width than the rest of the actuation element 14. This makes it possible for a sealing ring to extend across the actuation element 14, between the protruding sections 16, 17 (see also Fig. 6), which thus form a passage.
  • Fig. 8 shows the rear face of the actuation element 14.
  • the lower part of the rear face of the actuation element 14 is formed with an embedded recess 18.
  • the recess 18 is shaped with two inclined walls 19, 20 which are tapered along the direction of movement of the actuation element 14 in relation to the prongs 6 of the locking ring.
  • the prongs 6 are schematically indicated by means of broken lines in Fig. 8. During operation, the end sections of the prongs 6 are normally situated in the recess 18.
  • the walls 19, 20 limit the movement of the prongs 6.
  • the coupling member 1 can be inserted in the coupling sleeve 9 as has been described above.
  • the locking ring 5 is squeezed together slightly by the conical surface 11.
  • the prongs 6 of the locking ring 5 are allowed to move within the space which is formed by the recess 18 (see Fig. 8).
  • the locking ring 5 is locked in the groove 10 in the coupling sleeve 9.
  • the actuation element 14 is pressed down, i.e. towards the locking ring 5 in the axial direction. This forces the walls 19, 20 of the actuation element 14 to squeeze the locking ring 5 together.
  • the coupling member 1 may now be drawn out of the coupling sleeve 9.
  • the sealing ring 15 Due to the fact that a section of the sealing ring 15 extends between the protruding sections 16, 17, and due to the resilient property of the sealing ring 15, the sealing ring 15 flexes when it is acted upon by the protruding section 16. In this regard, the sealing ring 15 will act as a spring device which urges the actuation element 14 to be moved to its initial position after it is released.
  • the coupling device may be utilized in connection with electrical components, pneumatic and hydraulic connections, different types of fastening elements, sealing nipples and the like.
  • the coupling sleeve 9 be provided with conical, sloping guiding surfaces 11, but instead straight end surfaces may also be utilized.
  • the coupling member 1 may be rotationally fixed in a certain angular position in connection with the mounting of the coupling sleeve 9, or may alternatively be freely turnable through 360° around the longitudinal axis of the coupling member 1.
