PROBLEM TO BE SOLVED: To provide a piping joint provided with a function enabling easy and inexpensive confirmation by visual observation as to whether a male member is inserted and fitted into a regular position of a shaft hole of a female member or not. SOLUTION: A sealing member 18 is inserted and fitted into an inner wall surface of a second hole part 15 of a second cylinder part 11 of the female member in a closely adhering state. A bush member 35 is disposed in a closely adhering state on a wall surface of the shaft hole of the female member between an engagement piece 26 and the sealing member 18. Before inserting the pipe 40 into the shaft hole of the female member, the bush member 35 is locked by a second slit part 31b of a first cylinder part 21 and is made visible from the outside. The bush member 35 is moved inward in the shaft direction by being pushed by an annular projecting part 42 by the insertion of the pipe 40 into the shaft hole of the female member and the pipe 40 is inserted and fitted into the regular position within the female member, and thereby moving of an O-ring to one end side is regulated. The moving of the bush member 35 from the second slit part 31b to the second cylinder part 11 side can be confirmed through the second slit part 31b. |
