ABSTRACT:
Herein disclosed is a connector for connecting slender piping members. The connector comprises a connector body and a separate socket body. The connector body is formed axially therethrough with a smaller-diameter chamber leading to a communication hole in a connecting cylindrical wall at the leading end and a stepped larger-diameter chamber at the back of the smaller-diameter chamber. The larger-diameter chamber has its cylindrical rear circumference formed into an inwardly inclined retaining wall. The connector body has seal ring members fitted in the smaller-diameter chamber and a bushing member fitted at the back of the seal ring members. The socket body has generally L-shaped elastic pawl walls projecting integrally from the retaining wall in the larger-diameter chamber and opposed in the inserting direction to an annular wall at the rear end. The socket body has its slope retained in the vicinity of the root of the L-shaped bent portion. An annular ridged wall formed in the vicinity of the connecting end portion of a piping member fitted in the larger-diameter chamber is elastically retained under the pipe connected state by the leading ends of the pawl walls.
