ABSTRACT:
A tension-activated disconnecting coupling operates by having a plug portion penetrate and pick-up an expandable locking ring. On partial with withdrawal of the plug, the locking ring is carried into a confining region where expansion of the ring is constrained and the plug is effectively locked within the coupling. Applied tension thereafter overcomes an internal spring resistance and allows the locking ring to move out further, into a space where it may expand and release the plug.
