A has a receiving hole 15 into which the end is fitted. In the vicinity of the receiving hole 15, a large diameter portion 16 having an inner diameter larger than the receiving hole 15 is provided.
Is provided. The locking ring 17 is connected to the large diameter portion 16 of the joint body 14.
In addition, it is arranged coaxially with the joint body 14. This locking ring
As shown in FIG. 7, a plurality of locking claws 17a are provided along the inner periphery of the water supply pipe 17 and are engaged with the outer periphery of the water supply pipe. The O-ring 9 is disposed on the large-diameter portion 16 and
When it is inserted, it comes into close contact with its outer periphery. Nut member 18
Is screwed with a male screw engraved on the outer periphery of the large diameter portion 16 of the joint body 14, is disposed coaxially with the joint body 14, and

る。In this pipe joint, a pipe A is connected to a nut member.
By inserting it into the fitting body 14 from the 18 side, the locking ring
The locking claws 17a of the pipe 17 are deformed so as to be pushed outward by the pipe A and spread outward, and bite into the outer periphery of the pipe A. Thereby, the pipe A is connected and fixed without falling off from the pipe joint.

う。また、管継手毎交換しなければならないので、大き
な無駄が生じていた。However, with the former pipe joint, it is difficult to pull out the pipe A once connected, and the joint body 14 and the nut member 18 are adhered by an adhesive or the like so that they cannot be disassembled. Therefore, for example, when it is desired to replace an old pipe A with a new one, the pipe A must be cut, which requires a lot of labor for piping work. In addition, since each pipe joint must be replaced, a large waste is caused.

に繋がる恐れがある。In the latter type of pipe joint, it is difficult to intentionally pull out the pipe A. However, since the joint body 20 and the nut member 21 are not bonded by an adhesive or the like, the joint body 20 and the nut By disassembling the member 21, the locking ring 19 and the pipe A can be removed. However, since it is necessary to disassemble and reassemble again, it is also troublesome. In addition, this tube has a relatively large diameter if it is not properly tightened, and the tube A can easily come off when it is not necessary, which may lead to a serious trouble.

It has a plurality of locking claws 13a that bite into the outer circumference of the inserted tube A and lock. The locking ring 13 is formed such that its diameter increases with the displacement of the nut member 12 in a predetermined direction. That is, when the nut member 12 is tightened and displaced toward the spacer 10, the locking ring 13 is pressed by the contact portion 12a of the nut member 12 and the peripheral wall 11a of the concave portion 11 of the spacer 10, and the C-shaped one end thereof And the other end approaches and deforms so that the diameter becomes smaller.
Then, by loosening the nut member 12 and displacing the nut member 12 to the side opposite to the spacer 10, the pressing force for pressing the locking ring 13 decreases, and accordingly, the C-shaped one end of the locking ring 13 and The other end separates and deforms so that the diameter increases.

抜きが可能となる。The connection and fixing of the pipe A using this pipe joint are performed as follows. That is, when the nut member 12 is tightly tightened, the diameter of the locking ring 13 substantially matches the outer diameter of the pipe A to be inserted.
There is no need to loosen 12. Therefore, just by inserting the pipe A, the locking claw 13a pressed by the pipe A is deformed so as to expand outward and bites into the outer periphery of the pipe A. Thereby, the pipe A can be firmly connected and fixed. Also tube
When it is desired to pull out A, it is only necessary to loosen the nut member 12. As a result, the diameter of the locking ring 13 which substantially coincides with the outer diameter of the pipe A to be inserted becomes larger, and the locking claw 13a of the locking ring 13 does not lock on the outer periphery of the pipe A. Can be pulled out.

A can be fixed and unfixed.
Therefore, for example, when replacing an old pipe A with a new one, there is no need to cut the pipe A, and it is not necessary to disassemble the pipe joint, pull out the pipe A, and assemble the pipe joint again. It can be easily replaced without the need for a replacement. Furthermore, since it is not necessary to replace every pipe joint, the use efficiency of the pipe joint is improved. In this way, the pipe joint can firmly connect and fix the pipe A as long as the nut member 12 is not loosened, and can easily pull out the pipe A when necessary.
