Claims

[Scope of utility model registration request]

In a pipe joint that is joined by inserting a socket formed on one pipe into a socket formed on the other pipe, the taper part expands the inner periphery of the open end of the socket toward the back. At the same time, an annular protrusion protruding toward the center in the radial direction is formed at a position a certain distance back from this tapered part, and an annular locking ring that is placed in the receptacle and hugged by the receptacle is formed. The lock ring is provided movably in the tube axis direction between the protrusion and the tapered part, and an annular blade part is formed on the inner periphery of the lock ring to protrude in the radial direction and abut against the outer periphery of the insertion opening. A detachment prevention pipe joint characterized in that an annular groove portion that engages with a blade portion is provided at a position an appropriate distance from the tip.
