Claims

[Scope of utility model registration request]

It has a pipe fitting main body into which a pipe to be connected is inserted from the open end, and a press ring that is loosely fitted onto the outer circumferential surface of the connection part of the pipe to be connected and is screwed into the pipe fitting main body, and the press ring has a A pair of circumferential grooves are formed at the front and rear two locations with a required spacing, respectively, and have first and second tapered surfaces that gradually become smaller in inner diameter toward the front and rear end sides, respectively. A pair of retaining rings each having an edge portion supported on the inner side by a backup ring in a circumferential groove and slidably fitted to the outer circumferential surface of the connecting portion of the connected pipe are attached to the first and second taper rings. A recessed groove extending in the circumferential direction and formed to fit and lock the edge portion of each retaining ring is provided on the outer circumferential surface of the connecting portion of the connected pipe, and the recessed groove is located between both of the retaining rings to connect the pipe joint body and the pipe to be connected.
