ABSTRACT:
An improved locking element for a quick-connect coupling is designed for use in joining together tubular fluid conduits. The locking element comprises an annular segment and a plurality of annularly distributed resilient curled fingers which is sized to fit inside an annular cage mounted on one end of an inner coupling. The locking element of the inner coupling engages the flared end of an outer coupling when the couplings are telescopically fitted together.
