Claims

[Scope of utility model registration request]

A female thread is provided on the inner periphery of one end of the hole in the pipe fitting body, a contact part with a smaller diameter than the female thread is provided on the back side of the female thread of the hole, and a retaining ring having a male thread on the outer periphery is screwed into the female thread. A concave groove in which a substantially annular pressing member is movably inserted is provided on the inner periphery of the presser ring, and the surface of the concave groove on the side opposite to the spiraling direction of the presser ring is pressed so that the diameter becomes smaller as the side opposite to the spiraling direction A flexible tube with a wavy outer circumference and a retaining ring fitted to the end thereof is fitted into the presser ring, and one end of the retaining ring is pressed by a pressing member pressed by the pressing inclined surface. A coupling device for flexible pipes, in which the other end of the retaining ring is pressed against the inner abutment part of the female thread.
