  • Coupling for coaxial connection of fluid conduits
    Patent number: 6913294
    Abstract: A coupling is designed for sealingly connecting two fluid conduits such as automotive fluid lines in axial end-to-end relationship. The conduits have respective telescopically interengaging male and female end sections and the coupling comprises a base member to be carried on one of the fluid conduits and a retaining structure mounted on the base member and having two C-shaped arms which can be interconnected around the other conduit end section. A releasable lock acts between the arms to lock the retaining structure in engagement. In the locked condition the axially oriented abutment surfaces in the retaining structure engage peripheral shoulders on the conduits to prevent axial separation of the latter. The coupling can be fabricated from integral plastic components and preferably includes a guard arrangement to shield the releasable lock against inadvertent disengagement.
