ABSTRACT:
A compound coupling nut (60) mounted to a plug shell (10), first and second sets of detents (34, 84) arranged annularly and extending radially inward from one of the shell and/or the inner coupling sleeve, and a C-shaped detent spring (90) disposed radially-between the first and second detents, the detent spring having inwardly directed spring fingers (100) adapted to engage the ratchet teeth (34) and detent lugs (98) adapted to engage the arcuate detents (84), the detent spring (90) respectively, resisting and not resisting rotation of the coupling nut if rotated in one or the other directions, whereby as external coupling torques act on the coupling nut (60), the spring fingers (100) do not prevent rotation and as external uncoupling torques act on the coupling nut (60), the spring fingers (100) and the detent lugs (98) initially cooperate to resist rotation of the detent spring (90) and the coupling nut (60) until sufficient torque causes the detent lugs (98) to snap free, whereby uncoupling rotation of the coupling nut takes place.
