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 stepped smaller-diameter chamber, which is expanded to lead to a communication hole formed in a connecting cylindrical wall at the leading end, and a stepped larger-diameter chamber which is positioned at the back of the smaller-diameter chamber. The connector body is further formed with a pair of engagement holes or slots opposed to the circumferential wall of the larger-diameter chamber to form a retaining wall at the circumference of the rear end. The connector body has seal ring members at the side of the smaller-diameter chamber and a bushing member at the back of the seal ring members. The separate socket body has a pair of elastic pawl walls projected from the circumferential wall of the axial through hole in the larger-diameter chamber and inclined forward opposed to the front portion of the assembly direction. The socket body has its rear end annular circumference retained on the retaining wall. The piping member is formed in the vicinity of its connecting end with an annular ridged wall which is retained elastically by the leading ends of the elastic pawl walls when the piping member is in its connected state. The socket body includes: a cylindrical wall forming the root of the elastic pawl walls; cut-away apertures formed in positions opposed to the engagement holes in the vicinity of the intermediate portion of the cylindrical wall; tongue-shaped walls positioned in the cut-away apertures and leading integrally to the elastic pawl walls and the leading end of the cylindrical wall; and a stepped engagement groove formed backward and having its rear end on the retaining wall. |
