ABSTRACT:
A piping joint includes a male member or joint fastened to a female member or socket by locking pawls of a retainer sleeve onto pawl engaging portions. By pressing a flange by the tip ends of the pawls, the male member (joint) can be disengaged from the female member (socket) by reducing the diameter of the retainer sleeve and disengaging the pawls from the pawl engaging portions. A ring member is formed of an elastic material and is inserted between the retainer sleeve and a cylinder portion in a locked condition. A reduction of the diameter of the retainer sleeve is prevented by the presence of the ring member. Therefore, the connecting or detaching of the piping joint can be carried out in a condition where a holding force of the piping joint is maintained.
