A connector for male and female members, the connection being established by a stab-in action and being released by a rotational action. The connector includes a male member having an external helical groove, a female member having an internal helical groove, and a resilient helical coil received in the groove of one of the members and extending outwardly therefrom in the relaxed condition. The helical coil can have a circular or polygonal cross-section and has an end secured to the member carrying it to prevent gross displacement therebetween. The helical grooves in the male and female members having opposed, upwardly and inwardly tapering load-bearing surfaces receiving the helical coil therebetween in the connected condition. These tapering load-bearing surfaces can have the same or different angles of taper.
