ABSTRACT:
A novel fluid coupling assembly in combination with a fluid line provided with a controlled leak path. The fluid coupling assembly includes a coupling body 12 having generally concentric first and second bores 36, 38, of greater and lesser diameters, respectively, there being a radial surface 40 between the bores, the first bore also being provided with a generally cylindrical groove 44. A resilient retainer is assembly with in the generally cylindrical groove, the retainer having a plurality of prongs 52 which extend inwardly towards the second bore. A bushing 15 is force fit into the first bore between the cylindrical groove 44 and the radial surface. A seal 16 is disposed within the coupling body between the bushing and the radial surface. The fluid line which is adapted to be associated with a coupling is provided with a flange which is engaged by the free ends of the resilient prongs when the fluid line is fully assembled within the fluid coupling assembly to hold the fluid line in place, the fluid line being provided with a controlled leak path 74 which permits the discharge of fluid only when the end portion is not fully assembled.
