The invention relates to a corrugated pipe joint capable of securely connecting a corrugated pipe with a simple operation and capable of keeping a proper air-tight sealing state. In the corrugated pipe joint 1, a cylindrical joint main body 10 having an inner hole 11 into which a corrugated pipe T having annular furrows and ridges on its outer circumference is inserted, an air-tight packing 31, arranged in a joint main body inner hole, for tightly contacting with an outer circumferential surface of the corrugated pipe, a retainer 40, arranged in a joint main body inner hole, having a claw 43, of which diameter is enlargeable and contractable, engaging with an annular furrow part of the corrugated pipe when its diameter is contracted and a retainer pressing sleeve 50 for sliding in a rear direction and pressing the retainer to contract so that the claw of the retainer engages with the annular furrow part of the corrugated pipe. The retainer pressing sleeve is prevented from sliding in the joint main body inner hole in the rear direction till a tip end of the corrugated pipe reaches a predetermined position at a rear part of the joint main body inner hole.
