A pipe joint that is capable of achieving a sufficient bearing force against pulling without increasing the length of contact with a pipe and that has excellent appearance. The pipe joint is composed of a joint body (2) and a fixture (3). The joint body (2) is constructed by joining tubular insertion sections (2a) with joining sections (2b) in between, the insertion sections (2a) being inserted and fitted in a pipe (P), the joining section (2b) being a single circular tube or a joint body that is composed of circular tubes, the single circular tube and the joint body having the same outside diameter as the outside diameter of the pipe (P). The fixture (3) has an elastic body (4) having the outside diameter same as the inner diameter of the pipe (P), holding plates (5) arranged on both faces of the elastic body, a retaining metal member (6) provided next to one of the holding plates and where folded-back claws (6c) capable of biting into the inner periphery of a insertion section (2a) are provided on the heads of legs (6b) that extend axially from the peripheral edge of an annular plate section (6a), a bolt (7), and a nut (8). The bolt (7) passes through the center sections of the elastic body (4), the holding plates, and the retaining metal member (6), and fastens them with the nut (8). The fixture (3) is inserted from an end section of the pipe (P) and fixed at a position corresponding to the length of the insertion section (2a) with the retaining metal member (6) provided at the end section. |
