PROBLEM TO BE SOLVED: To provide a pipe fitting which securely prevents a socket member and a spigot member which are connected with each other from being extracted out in axial direction. SOLUTION: The pipe fitting is connected in such a state that extraction of axial direction of a case 1 and a pressing ring 5 is restrained by relatively turning the case 1 and the pressing ring 5 in circumferential direction so that an inner peripheral bulge part of the case 1 and an outer peripheral bulge part of the pressing ring 5 are engaged in axial direction with each other after fitting and inserting the case 1 and the pressing ring 5 in axial direction. In the pipe fitting, an end face 33b extending outward is formed in the case 1, an extension part 19 extending outward is formed in the pressing ring 5, and a piece 20 is attached to a place where the end face 33b and the extension part 19 are separated from each other in circumferential direction by relative turning, and the relative turning of reverse direction of the case 1 and the pressing ring 5 connected with each other is restrained by engagement of the end face 33b and the extension part 19 with the piece 20 after the case 1 and the pressing ring 5 relatively turn in one circumferential direction.
