ABSTRACT:
A connector for joining ends of tubular members having external grooves near the ends including a plurality of latching elements having inner projections for engaging the external grooves in the tubular members and external surfaces, a first cam ring having internal surfaces for mating with the upper external surfaces of the latching elements, a second cam ring having internal surfaces for mating with the lower external surfaces of the latching elements, threaded studs extending through said cam rings with a nut engaging each threaded end for forcing the cam rings toward each other, at least one of the upper or lower external surfaces of the latching elements being tapered so that the movement of the cam rings moves the latching elements into locking engagement with the tubular member grooves and a snap ring for biasing the latching elements radially outward.
