ABSTRACT:
A coupling for sealing a leak location in a pipe or pipeline by compressing against the pipe or pipeline a pair of annular gasket members fitted about the pipe or pipeline on opposite sides of the leak location comprising a first axial sealing pad disposed in a recess in an annular coupling member and a second axial sealing pad attached to a sealing plate which extends across an axial split in the coupling. The first and second axial sealing pads form an axial seal when the coupling is closed about a pipe or pipeline for preventing passage of fluid from between the annular gasket members to the outer surface of the coupling member through the axial split. The annular coupling member of the coupling has an axial split defined by first and second axial edges and comprises a first portion extending from the first axial edge to an axial shoulder which extends outwardly to a second portion. The second portion extends from the axial shoulder to a second axial edge to form the inwardly facing recess in which the first axial sealing pad is disposed.
