Claims

[Claims for Utility Model Registration] (1) A cylindrical pipe collar for interconnecting a pair of pipes, which has an annular sealing material on its inner circumferential surface at the center in the axial direction of the collar. A pipe collar with a circumferential groove for placement. (2) The circumferential groove is defined by a recess extending circumferentially on the inner circumferential surface and a pair of protrusions that are connected to both peripheral edges of the recess and whose top surface diameter is smaller than the outer diameter of the end of the tube. Scope of Claim for Utility Model Registration (1)
Pipe collars listed in section. (3) At each end of the pipe collar, the inner circumferential surface thereof allows an elastically deformable annular sealing material attached to the end of the pipe to enter the end, but prevent it from coming out from the end. Utility model registration claim No. 1, which is provided with a blocking hook-shaped protrusion
Pipe collars listed in section. (4) The pipe collar according to claim (3) of the utility model registration, wherein the protrusion extends continuously along the circumferential direction. (5) The pipe collar according to claim 3, wherein the protrusion is discontinuous along the circumferential direction.
