PROBLEM TO BE SOLVED: To provide a joint for connecting a corrugated pipe, which need not manufacture a seal material to fit the wavy shape of the corrugated pipe, and can accurately mount the seal material on the corrugated pipe without twisting the seal material, and can show a large holding force against a force in the direction of the coming-off of the corrugated pipe. SOLUTION: An engaging projection of a lock ring is inserted into an annular recessed portion of the corrugated pipe. The coming-off of the corrugated pipe from the joint body is prevented by the lock ring. In addition, an O-ring is brought into pressure contact with both side surfaces of the annular recessed portion by holding the O-ring in the compressed state between a spigot portion inserted into the joint body and a retainer fitted in the joint body. Further, a part of the O-ring in the neighborhood of its inside diameter is inserted into the annular recessed portion so as to prevent the coming-off of the corrugated pipe by the O-ring.
