PURPOSE: A joint pipe using a packing of hollow pipe type is provided to ensure the watertight seal because the packing is pressed by a pusher and deformed to be convex inward. CONSTITUTION: A joint pipe comprises a body(10), a fastener(20), packing(30), and a pusher(40). The body forms a flow path and a pipe(P) inserted into the body is coupled with the fastener. The packing in the shape of hollow pipe is inserted and supported inside the body and surrounds the exterior of the pipe. The pusher is installed in one side of the packing and moved along the exterior of the pipe in the longitudinal direction. As the fastener transfers the pusher to press the packing, the packing is deformed to be convex inward and closes the pipe.
