PROBLEM TO BE SOLVED: To provide a corrugated pipe joint permitting a connecting operation with a good construction property without using tools such as a spanner and a wrench, etc. SOLUTION: The corrugated pipe joint 10 comprises a joint body 11, retainers 15, a case 19 and the like. Each retainer 15 is a member made from stainless, in which a locking part 15a, a pawl 15b and a connection 15c are formed integrally with one another. The locking parts 15a of the retainers 15 are integrally linked with one another by ring-shaped elastic members 14. When the case 19 is threaded into the joint body 11, a taper part 19a at the lower end of the case 19 makes contact with the tapered surface 15d of each retainer 15, which is in turn tilted in the direction of insertion of a corrugated pipe T. When the tapered part 19a is in contact with the tapered surface 15d, each retainer 15 is not tilted in the opposite direction (withdrawal direction) to the direction of insertion of the corrugated pipe T. This allows a connecting operation to be carried out while preventing inadvertent disconnection of the corrugated pipe T.
