PROBLEM TO BE SOLVED: To provide a pipe joint excellent in stability and durability as compared with a conventional one. SOLUTION: This pipe joint has a holding member 3 for gripping a pipe 1 in a joint body 2, and a releasing member 4 for plunging the holding member 3 into the deep side. When the holding member 3 and the inserted pipe 1 are moved in the coming-off direction, the holding member 3 reduces its diameter along a taper surface 7 in the joint body 2 to cut into the pipe 1. The pipe joint has, in the joint body 2, a stranding face 8 for increasing the diameter of the deep-side end or/and the front-side end of the holding member 3. At least either one of the stranding face 8 and an opposite abutting surface 9 at an end of the holding member 3 abutting on each other is shaped into a curved surface. COPYRIGHT: (C)2004,JPO
