An improved coupling assembly includes a plug on which a resiliently compressible lock ring is disposed. As the plug is inserted into a socket, a stop ring in a socket chamber deflects the lock ring radially inwardly from an expanded condition to a contracted condition to enable the lock ring to pass through a circular central opening in the stop ring. Once the lock ring has moved axially inwardly of the stop ring, the natural resilience of the lock ring causes it to expand radially outwardly to hold the plug in the socket chamber. When the coupling is to be disconnected, the plug is pushed further inwardly and the lock ring is radially compressed by a movable cam ring slightly smaller than the stop ring. The cam ring compresses the lock ring to the contracted condition. The lock ring and the cam ring are then free to move backwards and the cam ring can pass through the opening in the stop ring as the plug is pulled outwardly. |
