Abstract
An improved tubular connector including a first tubular member, a second tubular member, said members having external grooves near their ends which are to be joined, a plurality of latching segments having internal projections adapted to engage in the grooves of both said first tubular member and said second tubular member and also having external tapered surfaces, an actuator ring having an internal tapered surface matching and engaging the external tapered surfaces of said latching segments, movement of the actuator ring in one direction wedging said segments into tight latching engagement with said grooves on said tubular members and movement in the other direction releasing said segments to allow them to disengage from said grooves on said tubular members, an external retaining groove in one of said tubular members, and a split ring positioned in said external retaining groove and engaging said actuator ring to exert a force thereon which retains it in each of its extreme positions.
