Claims

[Scope of Claim for Utility Model Registration] A joint body having a cylindrical connection port into which a corrugated flexible resin tube is inserted, and a nut body that is screwed into the connection port while being fitted onto the flexible resin tube. ,
and a retaining ring set inside the connection port, the retaining ring having an annular protruding part facing inward at the front end of the cylindrical part, and an inner peripheral diameter of the protruding part. The nut body is formed of an occluded cylindrical body larger than the outer peripheral diameter of the resin flexible tube, and a tapered surface is formed on the outer periphery of the overhang, and the nut body is screwed into the connection port. It has a contact part that pushes the retaining ring and allows the retaining ring to contract in diameter when A tapered guide surface that advances the retaining ring while reducing its diameter radially inward, and a flexible resin tube that engages with the extended portion of the contracted retaining ring and is advanced. It is characterized by having an annular protrusion that abuts the end, and a protrusion that is provided on the inner periphery of the protrusion and that fits into the end of the flexible resin tube and supports the end from inside. Fittings for flexible resin pipes.
