Claims

[Scope of utility model registration request]

Ends 12a, 12 of the first pipe P1 and the second pipe P2
In the pipe joint structure in which pipes b are connected via an O-ring 5, a bead portion 2 is formed at one end portion of the first pipe P1, and a bead portion 2 is formed at the end portion of the second pipe P2, beyond the bead portion 2. a protruding portion 10 extending from the outside, a contact portion 11 still in contact with the bead portion 2, an extension portion 13 extending along the end portion 12a of the first pipe P1, and a window opened at a predetermined location on the outer periphery of the extension portion 13. 14, and this first pipe P
1 and the second pipe P2 against the abutment part 11 and pressurizes the second pipe P2 and the first pipe P2 toward the bead part 2; When the abutment part 11 makes contact, it passes through the window part 14 and locks into the engagement recess 17 of the first pipe P1, and when the bending point 19 is pressurized by the pressure member 18, it is reversed. A pipe joint structure in which the pipes are connected by a locking member 15 having an elastic locking pawl 20 that expands radially outward.
