A water pipes connecting device is provided to improve watertight of a water pipe by installing a sealing ring, whose inner diameter gets smaller downwards, around the water pipe. A water pipes connecting device comprises a connector(200), a sealing ring(310), a stopper ring(320), a pressing gasket(330), a ring washer, and fastening members(350,360). The stopper ring includes a hole and a plurality of protrusions. A water pipe(100), which is inserted to the connector, passes through the hole of the stopper ring. The protrusions of the stopper ring contact with the outer surface of the water pipe and protrudes longer from the inner surface of the hole from the top to the bottom. The sealing ring has an inner oblique portion(310a) whose diameter gets narrower from the lower area to the bottom end area. |
