摘要： PROBLEM TO BE SOLVED: To provide a corrugated pipe joint having such advantages that the number of parts disposed off in connection operation can be reduced or the pipe joint can be re-used by disassembling without cutting the end part of a corrugated pipe after installation. SOLUTION: In this corrugated pipe joint 1, since a retainer holder 31 is slidably positioned at a lock position by a spacer 50 before installation, such an erroneous operation that the retainer 41 is locked before the corrugated pipe T is inserted can be prevented. Since, in the installed state, the retainer holder 31 can be slid to the lock position with the spacer 50 installed between the retainer holder 31 and a body 3, the spacer 50 does not become a waste part in installation. In addition, since, after the installed state, the retainer holder 31 can be slid beyond the lock position to an unlockable state after the spacer 50 is released from the retainer holder 31 and the body 3, the joint 1 can be disassembled without damaging the tip part of the corrugated pipe T.
