ABSTRACT:
A connector for slender piping members is disclosed. A spacer, seal rings and a bushing are inserted into the end of one piping member to be connected. The leading end portion of the one piping member is fitted in the outer circumference of the bushing. The end portion of the other piping member to be connected is pushed into the axial core of the bushing. An annular flange portion formed on the outer circumference of the other piping member is held in abutting engagement with an annular wall of a socket body, which in turn is abutted against the front face of the bushing. The circumferential wall portion of the one piping member is clamped by stepped oblique walls inside the connector body. The socket body has a plurality of elastic pawl walls projecting obliquely in the connecting direction. An annular wall formed integrally with the pawl walls is engaged by a retaining wall of the connector body. Thus, the piping members are connected by engaging the flanged wall of the piping member with the pawl walls of the socket body.
