Abstract

PURPOSE: To make it possible to prevent the looseness of a holding power even when a drawing force acts upon a pipe by forming a pipe joint comprising a cylindrical joint body; a cylindrical socket member coupled to the joint body; a grip ring within the socket member; and a spring between the joint body and the grip ring. CONSTITUTION: A pipe joint comprises joint body 10; socket member 20 and grip ring 30. Joint body 10 has a through hole 11 for pipe P formed at an end portion in the axial direction. Socket member 20 can advance and retreat freely with respect to joint body 10. Grip ring 30 fits to the end portion of pipe P and disposed within socket member 20 together with spring 40. The inner face of socket member 20 and the outer face of grip ring 30 are taper faces. The diameter of grip ring 30 can be enlarged or reduced, and when the diameter is reduced, the protrusion 32 formed on the inner peripheral surface of grip ring 30 bites into the end portion of pipe P. Therefore, when a force in a drawing direction acts upon the pipe, the grip force increases.
