A duplex pipe fitting includes a fitting main body 1 and a pair of coupling members 2 which are threaded to both ends of the fitting main body 1. The coupling members 2 are threaded to the fitting main body 1, so that two pipes P are connected to each other with the fitting main body 1. Each coupling member 2 includes a holding portion 24 including a holding surface consisting of a pair of or a plurality of pairs of planes facing each other so that it can be held with a general fastening tool. When a rotational torque for tightening the coupling member 2 to the fitting main body 1 reaches a value indicating the completion of fastening, at least a part of the holding portion including the holding surface is separated and the pipe connecting is complete. |
