Claims

[Scope of utility model registration request]

Between the pipe and the cylindrical joint body into which it is inserted,
An annular elastic seal member is arranged to elastically seal the space between them, and an annular retainer and a retaining ring are sequentially arranged on the axially outer side of the elastic seal member, and are screwed onto the end of the joint body. and a push ring that presses the annular elastic seal member in the axial direction by screwing to apply a sealing force, and has a press ring formed on the inner periphery with a tapered surface that reduces the diameter of the retaining ring and bites into the pipe. In the pipe joint, an extending portion is formed on the outer periphery of the annular retainer to be bent inward in the diametrically expanding direction and axially by being pressed by the pushing ring from the middle of the screwing of the pushing ring to the screw tightening completion position. A tube characterized in that a regulating protrusion is formed on the radially inner side of the part to abut against the axially inner end surface of the retaining ring before the screw tightening completion position of the push ring and to restrict at least the forward movement of the retaining ring.
