    Abstract: A pipe connector with helically threaded (49, 57) frustoconical pin (10) and box (30) surfaces. The connector is axially (78) snapped together, but is rotated for disengagement. Centralizing surfaces (150, 152) on each thread form abut opposing crests (62, 54) to maintain concentrically, thereby detering disengagement under bending moments.
