Claims

[Scope of utility model registration request]

A cylindrical housing 1 that is fitted over both ends of the pipes A and A' to be connected;
Two seal rings 2, 2 are installed in the two inner circumferential grooves 1a, 1a of the housing 1 and fit into the connected pipes A, A', respectively, and the housing 1 is connected to both the connected pipes A, A. The housing 1 includes a fixing means 6 for fixing the two inner circumferential grooves 1a, 1a to each other, and the inner surfaces 1b of the two inner circumferential grooves 1a are inclined inwardly toward the center, and the outer surface 1c has a circumferential direction. A plurality of recesses 4 are formed at equal intervals, and each recess is provided with a radial threaded hole 5 penetrating through the bottom of the recess, while the inner surface 2b of the seal ring 2 is formed on the inclined surface 1b of the inner circumferential groove. A ring-shaped pad 3 is affixed to the correspondingly inclined inner surface, and the fixing means 6 is a chip with an inner claw 7' which is accommodated in the recess 4 and whose outer surface side engages with the seal ring pad 3. 7 and a presser bolt 8 screwed into the screw hole 5. By tightening the presser bolt 8 and pressing the tip 7 from behind, the seal ring 2 is compressed and the connected pipe A is closed.
, A' and the inner surface 1b of the concave portion are brought into strong pressure contact, and at the same time, the tip claw 7' is bitten into the outer surface of the pipe to be connected and fixed.
