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. The pipe insertion hole is adapted to comprise a diametrally large part formed on the opening side of the joint body and a diametrally small part continuous with the large part; a hollow cylindrical body whose inner diameter equal to the diameter of the small part is inserted into the diametrally large part; and an annular groove for inserting a sealing member is formed between the inward edge surface of the cylindrical body and a stepped boundary surface between the diametrally large part and diametrally small one.

DETAILED DESCRIPTION What is claimed is: 1.
A pipe joint comprising, in combination with a pipe to be joined,: a joint body provided with a pipe insertion bore, said pipe insertion bore having a large diameter portion open at one end to the outside of said joint body and having a diameter greater than the outer diameter of said pipe to be joined, and a small diameter portion inwardly of said large diameter portion communicating with a connecting bore of said joint body and having a diameter equal to the outer diameter of said pipe to be joined, a first annular step being formed between said large and small diameter portions, and a second annular step being formed between said small diameter portion and said connecting bore; a hollow cylindrical body defined by cylindrical walls provided with means to allow communication through said walls and having an inner diameter equal to the diameter of said small diameter portion of said pipe insertion bore, inserted in said large diameter portion of said pipe insertion bore so as to define an annular groove between an inner end of said hollow cylindrical body and said first annular step; an annular resilient sealing member interposed in said annular groove for tightly sealing between said pipe insertion bore and an outer periphery of said pipe to be joined when said pipe is joined therein; annular packing means disposed in said small diameter portion of said pipe insertion bore between said second annular step and a distal end of said pipe to be joined when said pipe is inserted in said pipe insertion bore; at least one fixing hole formed in said joint body tangentially of said large diameter portion of said pipe insertion bore, an inner side portion of said fixing hole opening into said large diameter portion; and screw means adapted to engage with said fixing hole and to pass through said means in said wall to form recesses in an outer periphery of said pipe to be joined, whereby said pipe to be joined may be inserted through said inner diameter of said hollow cylindrical body and into said small diameter portion of said pipe insertion bore and said screw means engaged in said fixing hole, means in said wall and said recesses thereby formed in said pipe in order to join said pipe to said joint body
