摘要：An improved coupling assembly includes a plug member which is held in asocket chamber by a lock spring having a plurality of turns. The turns of the lock springresiliently grip a plurality of turns of a helix on the outside of the plug member to holdthe plug member in the socket chamber. To promote a secure-gripping engagementbetween the turns of the lock spring and the helix, the turns of the lock spring have thesame pitch as the helix. The lock spring can be resiliently flexed to increase the insidediameter of the turns of the lock spring from a free diameter which is smaller than theexternal diameter of the helix to a diameter which is larger than the outside diameter ofthe helix to enable the plug member to be readily inserted into the turns of the lockspring. The lock spring is then released so that its natural resilience causes its turns togrip the helix formed on the outside of the plug member.
