ABSTRACT:
An improved coupling assembly includes a plug and socket which are connectable to interconnect a pair of fluid conduits. When the coupling is disconnected, resiliently deflectable spring fingers on a plug body are disposed in a retracted position. When the coupling assembly is to be connected, the retracted spring fingers are inserted through an opening into a socket chamber. A slide is then moved axially toward the socket to resiliently deflect the spring fingers outwardly away from the plug body to an extended position in which outer end surfaces on the spring fingers are engageable with an annular stop surface in the socket chamber. When the coupling is to be disconnected, the sleeve or slide is moved axially away from the spring fingers and their natural resilience causes them to move inwardly toward the plug body so that the outer ends of the spring fingers can pass through the opening as the plug is withdrawn from the socket chamber.
