【Example】

 Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 shows the connection portion of the socket pipe of the present invention. The socket pipe 1 made of vinyl chloride resin has a socket having an expanded portion into which another pipe to be connected to the end is fitted. 2 is formed, and a projecting portion 3 that extends like a tongue along the axial direction is formed on the lower peripheral edge of the end portion of the receiving port 2. The inner surface of the projecting portion 3 is integrally formed so as to be flush with the inner surface of the receiving port 2, and the projecting width thereof is a width within about half of the peripheral edge of the receiving port 2 and the projecting length thereof. The length is about 2/3 of the diameter of the socket.

The socket 2 of the socket tube 1 is fitted and connected with another tube 4 shown as a phantom line in the drawing, which is used as a connection wire. 4 is fitted into the receiving port 2 while contacting the inner surface of the projecting portion 3.

Therefore, by this fitting, the pipe 4 is guided by the protruding portion 3 and slides on the inner side surface of the protruding portion 3 so that it can be accurately fitted into the receiving port 2 and connected at a predetermined position. By this sliding, the adhesive applied to the pipe 4 adheres to and adheres to the inner surface of the receiving port 2 ', whereby a strong connection can be achieved.
