ABSTRACT:
A quick-connect fitting assembly is disclosed for releasably connecting a pair of fluid conduits in fluid communication with one another. A socket portion on one of the fluid conduits is adapted for receiving the other fluid conduit inserted longitudinally into the socket portion. A laterally-extending protuberance on the inserted fluid conduit is longitudinally restrained by a retaining assembly generally adjacent the fluid socket, with the retaining assembly including one or more resilient spring of barb members longitudinally interlocked with the inserted fluid conduit. A pair of collar members are longitudinally interconnectable with one another, either by a threaded engagement or by a "bayonet-type" engagement, to releasably restrain the assembly in a connected condition. Such collar members can be provided with a feature by which complete disconnection of the fluid conduits is substantially prevented until any internal fluid pressure is relieved, at which time the fluid conduits can be completely separated.
