摘要： PROBLEM TO BE SOLVED: To provide a corrugated pipe joint for facilitating the jointing work even in a small space without using a spanner and a wrench or the like. SOLUTION: This corrugated pipe joint 10 is provided with a case 11 formed of an inner case 12 and an outer case 15. A retainer 21 is arranged between the inner case 12 and the outer case 15. A connecting nut 32 of a joint body 31 is connected to the outer case 15. A spring receiver 51 to be displaced in the axial direction by the spring force of a coil spring 45 is housed in a body main body 35 of the joint body 31. Before connecting a corrugated pipe, a key 57 of the spring receiver 51 is engaged with a key groove 37 of the body main body 35 so as to lock the spring receiver 51 in the axial direction. After inserting the corrugated pipe, the case 11 and the joint box 31 are relatively turned so that the key 57 of the spring receiver 51 enters a key groove 17 of the outer case 15.

摘要： PROBLEM TO BE SOLVED: To provide a corrugated pipe joint allowing a worker to easily perform connecting works in a narrow space without using a spanner and a wrench. SOLUTION: In a state where the corrugate pipe T is inserted and sufficiently pushed in an inner hole 13 of an inner case 12, a claw 23 of a retainer 20 is engaged with an annular recess portion outside the corrugate pipe T so that the corrugate pipe T is in a temporarily locked state and prevented from being pulled out. Then, when the worker draws out the corrugated pipe T upward by hands, the lock between the outer case 15 and the retainer 20 by a stop ring 30 is released, an outer ring groove 22a of the connecting sleeve part 22 of the retainer 20 and regular fixing groove for the connecting end portions of the inner/outer cases 12 and 15 are faced to each other, and the stop ring 30 is disposed therein to fix the retainer 20 in the ease 11. In a state where the retainer 20 is fixed thereto, the outer circumferential tapered face 27 of the retainer 20 abuts on the internal circumferential tapered face 19 of the outer case 15 so that respective segments 25 of the retainer 20 are contractedly fitted therein so as to firmly prevent the corrugate pipe T from being pulled out.

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.

摘要： PROBLEM TO BE SOLVED: To provide an insert type pipe joint capable of providing secure sealing by merely inserting a bellows pipe into a joint body, and having a simple and safe structure.
SOLUTION: This insert type pipe joint for connecting the bellows pipe F having recessed and projecting portions 18, 20 in corrugated form on an outer periphery, comprises: a joint main body 26 in which a pipe insertion aperture 24 for inserting the bellows pipe is formed and an inner wall surface is stepwise formed; a nut member 30 in the ring shape connected to a leading end of the joint body; a packing member 31 in the ring shape slidably arranged on the inner wall surface of the joint body; a retainer member 48 interposed between the nut member and the packing member, with an inner diameter of the retainer larger than that of an outer diameter of the bellows pipe, and capable of diametrically contracted by inserting the bellows pipe into an inside thereof; and a stop member 44 arranged on a base portion of the packing member for locking the bellows pipe by engaging with the recessed portion of the inserted bellows pipe. The nut member is formed with a fallout preventing taper surface 56 which deforms the retainer member in a diametrically contracting direction when a force is exerted to the bellows pipe in a drawing direction and pushes it into a recessed portion of the bellows pipe.
