１から抜け外れることはない。In addition, when this synthetic resin pipe is used as a connecting pipe that connects the drainage basin and the main sewer pipe, even if the insertion portion 2 is strongly pushed into the back of the receiving portion 1 due to ground subsidence, etc. Including part 2
Is locked by the locking piece 42 of the locking ring 4 so that further insertion is restricted so that it does not collide with the enlarged diameter portion 22 of the receptacle 1. Further, since the receiving port 1 is formed such that the inner diameter of the receiving port inlet is smaller than the outer diameter of the locking ring 4, the locking ring 4 can receive the receiving port even if the insertion part 2 is pulled out. It does not come off from part 1.
次に、第３図及び第４図に基づいて第２実施例を説明す
