Abstract: A pipe joint comprising a joint body provided with an insertion hole into which a pipe to be joined is inserted to be retained and a screw member adapted to engage with a fixing hole bored in the joint body and to form a recessed part on the outer periphery of the pipe by the engagement thereof with the joint body. Turning direction of the screw member conforms to pipe insertion direction. When joining two pipes together, a set of screw members for tightly fixing the pipes to the joint body respectively are provided in such an arrangement as perpendicular with each other. A boring member such as a drill is provided on the tip of the screw member so as to form the recessed part on the periphery of the pipe by cutting.
