To surely catch the outer circumferential face of a pipe body with an eccentric diameter by two streaks of claw parts by automatically aligning a pull-out prevention ring corresponding to the eccentric diameter of pipe body, when an eccentric pipe joint is inserted, and to have a large drawing force by positioning an application point toward the central part side of a joint body and concentrating at one point on the central axis line.

The joint body is formed by having a stopper projecting inward in the longitudinal central part and sealing members installed in the internal circumference in positions spaced at prescribed intervals in the both sides of the stopper. The joint body is provided with an annular recess part having an annular tapered face contracted toward a socket side in its circumference, and the pull-out prevention ring installed in the annular recess part. The pull-out prevention ring is so formed that two streaks of claw parts having insertion sides inclined and drawing sides vertical to the central axis are projected to the central axis side in the circumference, and the outer circumferential face is formed into an arc face of a prescribed curvature radius with the application point positioned toward the central part of the joint body.
