PROBLEM TO BE SOLVED: To easily insert a pipe body and to complete connection without moving the pipe body in a direction opposite to the insertion direction of the pipe body.SOLUTION: A support means 3 abuts on a surface 2c on a side where a locking pawl 2a is obliquely protruded in the outer peripheral part 2b of a locking ring 2 and supports the outer peripheral part 2b, thereby elastically deforming the outer peripheral part 2b as the pipe body B is inserted, to move the locking pawl 2a in a pipe insertion direction. When the insertion of the pipe body B is completed, the outer peripheral part 2b is elastically restored and the locking pawl 2a is moved in a pipe release direction and bites the outer peripheral surface B1 of the pipe body B. In this state, a stopper means 4 abuts on a surface 2d opposite to the side where the locking pawl 2a obliquely protrudes in the outer peripheral part 2b of the locking ring 2, and supports the outer peripheral part, thereby preventing the pipe body B from moving in the pipe release direction even when the pipe body B is drawn in the pipe release direction. |
