Claims

[Claims for Utility Model Registration] 1. A circumferential groove 7 is formed on the outer peripheral surface near the end surface of the pipe 4,
In this circumferential groove 7, there is a C-shaped pullout for preventing the cap nut 6 from coming out by coming into contact with the engagement part 6a for preventing the cap nut 6 for connecting the pipe from being pulled out. This is a mounting structure of a cap nut for connecting a pipe in which a stopper 8 is fitted and held, in which the abutment surface 8a of the stopper 8 to the stopper engagement part 6a is displaced toward the tube end as the outer circumference approaches. The mounting structure of the cap nut for pipe connection is formed in an inclined position. 2. The mounting structure for a cap nut for pipe connection according to claim 1, wherein the retainer 8 is circular in cross-sectional view.
