ABSTRACT:
An improved coupling assembly includes a socket assembly which telescopically receives a plug to connect a pair of conduits in fluid communication. The plug is movable from a disengaged position to a storage position in which the plug is supported by and is telescopically disposed in the socket assembly. The plug can be moved further into the socket assembly to an engaged position in which the conduits are connected in fluid communication. The plug is securely held in the engaged position by locking elements. The plug is releasably gripped in the storage position by a plurality of detents. The detents are mounted on a sleeve which extends through an opening in a faceplate. An actuator flange is disposed on an outer end portion of the sleeve to enable it to be readily depressed. The fluid which is to be conducted through the coupling assembly is identified by the indicia on the sleeve and by similar indicia on the mounting plate. The socket assembly is constructed in two sections with an interlock to prevent connection of an outer socket section with a wrong inner socket section.
