Claims

[Scope of Claim for Utility Model Registration] A flexible pipe joint for connecting a right cylindrical pipe made of a flexible material, which is approximately cylindrical in shape and has a thread for a nut at one end;
A tapered inner circumferential surface that becomes smaller in diameter as it goes deeper toward the inner circumferential surface of the one end, a joint body that has a stepped portion at the back of the tapered inner circumferential surface and has a width across flats parallel to the outer circumferential surface, and is approximately cylindrical. The shape has a flange at one end of the inner circumferential surface, an outer surface on the outer circumferential surface of the one end side that follows the tapered inner circumferential surface of the joint main body, and at least two points in the longitudinal direction at two or more locations in the circumferential direction. a retainer having a cutting part where the flange part is cut and the end opposite to the flange part is not cut; a screw threaded into the nut screw of the joint body;
A joint for a flexible pipe, comprising: a nut having a width across parallel to an outer circumferential surface; and a cylindrical stiffener that abuts a stepped portion on an inner circumferential surface of the joint body.
