ABSTRACT OF THE DISCLOSURE An electrical connector reconstructed in part to permit lanyard quick release in umbilical usage includes a collet and a detent shell. The collet has a base, a sort of undulating side extending from the base to a flange-lip extending radially inward at the top of the side (when seated on the base), the flange-lip having keyways corresponding to keys on the barrel of the recep- tacle. The collet is divided into a number of separate arc lengths, desirably at least three. The coupling ring has pro- visions for attaching a lanyard. Also an internal sloping end por- tion which can ride over the collet base but not the collet side. A detent shell fits partially inside the opening in the coupling ring. This detent shell has keys corresponding to those on the coupling nut and a nose which can slide underneath the collet base and side. The ring coupling and detent shell are resiliently held together so that a lanyard can pull the coupling ring back over the detent shell. The collet arc lengths provide rocker action under the cooperative force of the coupling ring internal sloped end and the detent shell nose. The rocker motion causes the flange-lip diameter to decrease, after the flange-lip is beyond the barrel keys, and frictionally lock the flange-lip and keys, placing the connector in locked/mated condition. Pull of the lanyard force- fully moves the coupling ring toward the detent shell. The inter- nal sloped end and conical nose cooperate to open the diameter of the flange-lip; the collet slips over the receptacle keys and the receptacle section and plug section are unlocked. Continued axial backward movement unmates the two sections, providing the desired quick release, that is, unlock/unmate, action.
