SINGLE OPERATION JOINT FOR FLEXIBLE TUBE

摘要

PROBLEM TO BE SOLVED: To combine slip-off preventing performance of a joint and a flexible tube sealing performance, and fire resistance of a sealing part by joining the joint and the tube to each other in a single operation only by inserting the flexible tube. SOLUTION: A taper surface 37 is formed on the inner periphery of a pressing ring 25, and an annular retainer 44 constituted of a press molded article is arranged on the inner peripheral side of the taper surface 37. In the retainer 44, a projecting part 46 is elastically extended by an angled part 4 of a corrugated pipe 2 when a flexible tube 1 is inserted, and the projecting part 46 is engaged with a root part 5 of the corrugated pipe 2 by the passage of the angled part 4. A sealing material 21 in a cylindrical main body 11 can seal the angled part 4 of the corrugated pipe 2 and at least partially formed of a fire resistant part 22.
