If there is a little extra space for insertion, that is, an extra space for the wall thickness of the branch pipe holding collar 2b,
It becomes possible to connect the drain branch pipe 4 to the branch pipe connection port 1e. Moreover, when the drain branch pipe 4 is connected, the engaging flange 2a at the rear end of the connecting pipe and the locking flange 1f at the end of the branch pipe connecting port engage with each other with the ring-shaped packing 5b sandwiched therebetween. It does not come out of the pipe connection port 1e. In addition, branch pipe connection port 1e
The watertightness between the connecting cylinder 2 and the drainage pipe 2 is maintained by the ring-shaped packing 5b sandwiched between the locking collar 1f and the engaging collar 2a. Since it is held by the ring-shaped packing 5a fitted in the groove 2c on the inner circumference of the holding collar 2b, it is possible to sufficiently prevent leakage of water and intrusion of unknown water from the connecting portion.

It can be connected to the connection port 1e, and in the connected state, the engagement flange 2a at the rear end of the joint pipe engages with the locking flange 1f at the tip of the branch pipe connection port, so that the joint pipe 2 is separated from the branch pipe connection port 1e. There is no way out. The ring-shaped packings 5a and 5b fitted in the recessed grooves 2c and 2c of the branch pipe holding collar 2b at the tip of the connecting cylinder and the engaging collar 2a at the rear end of the connecting cylinder are connected to the outer circumference of the drain branch pipe 4, respectively. Since the watertightness is maintained by closely contacting with the outer circumference of the branch pipe connection port 1e, it is possible to sufficiently prevent leakage of water or intrusion of unknown water from the connection portion.
