PROBLEM TO BE SOLVED: To provide a pipe joint of a slip-on type, in which the pipe joint can be easily extracted by manpower by workers at site even when the pipe joint is strongly fixed, and in which the pipe joint can be smoothly extracted without applying excessive force to it. SOLUTION: An insert port 3 is inserted into a receiving port 2 to connect a pipe joint 4, and cylinder bodies 8 are respectively disposed in an axial direction on both side surfaces of it. The respective cylinder bodies 8 are locked to an outer surface of the pipe joint 4, in such a way that they cannot be moved in the axial direction at least toward the receiving port side. In each cylinder body 8, a rod 9 is axially slidably inserted. An insert port side end of the rod 9 is engaged with an outer surface of the insert port 3 through an engagement member 15 in such a way that it is not relatively moved at least toward the insert port side. A tightening tool 11 is provided between the receiving port side end of the rod 9 and the cylinder body 8, and the rod 9 is pushed from the cylinder body 8 toward the insert port end by the tightening tool 11. The insert port is thus extracted from the receiving port by this motion. COPYRIGHT: (C)2005,JPO&NCIPI
