SEPARATION PREVENTION JOINT

To provide a separation prevention joint with improved separation prevention effect.SOLUTION: A separation prevention joint has a protrusion 3 provided at an insertion port of an insertion side pipe body 1, and a retaining member 4 provided on the inner surface of a socket of a receiving side pipe body 2, and prevents separation of pipe bodies by engagement between the protrusion 3 and the retaining member 4. When pull-out force is applied to the insertion side pipe body 1 and the receiving side pipe body 2 in a connection state to cause relative displacement in a pipe axial direction, separation prevention effect associated with the engagement occurs at a plurality of locations in the pipe axial direction.SELECTED DRAWING: Figure 1 【課題】離脱防止効果を向上した離脱防止継手を提供する。【解決手段】挿し側管体１の挿し口に設けられた突起３と、受け側管体２の受口の内面に設けられた抜け止め部材４と、を有し、突起３と抜け止め部材４との係合によって管体同士の離脱を防止する離脱防止継手において、接合状態の挿し側管体１と受け側管体２に引き抜き力を作用させて管軸方向に相対変位させた際に、前記係合に伴う離脱防止効果が管軸方向の複数箇所で生じる構成とする。【選択図】図１
