PROBLEM TO BE SOLVED: To provide a fluid pipe connector with improved torsional prevention ability. SOLUTION: At least one substantially, axially symmetrical seal formed as at least one axially symmetrical protuberance is provided on the inside surface of a connector body 10. At least one seal land 24 is provided on the outside surface of the connector body in a position adjacent to the substantially, axially symmetrical seal 16. A plurality of the protuberances 28, 32 for torsional prevention are provided on the inside surface of the connector body, the protuberance for torsional prevention is made to have a frictional surface resistant to the torsion between the pipe connector and a fluid pressure conduit. Moreover, at least one torsional land is formed on the outside surface of the connector body at a position adjacent to the protuberance for torsional prevention. The pipe connector is also made to include a ring being fixed fittingly on the connector body, this ring is locked to the seal land and used to lock the seal to the outside surface of the fluid conduit by pushing, and is locked to the torsional land 18 and used to lock a plurality of the protuberances for torsional prevention to the fluid pressure conduit by pushing. |
