IMPROVED PIPE COUPLING WITH BUILT-IN GRIP

摘要

A pipe coupling including an annular clamp having an opening at least one end of its axial length for inserting therein a pipe, the annular clamp including two clamp members, an annular inclined surface extending axially from each of the clamp members, a wedge-shaped gripper arranged for sliding and abutting against the annular inclined surface, and a fastener that fastens the clamp members towards each other in a direction transverse to the axial length so as to apply a radially-inward clamping force on the pipe inserted in the opening and a radially-inward clamping force on the annular inclined surface that moves and wedges the wedge-shaped gripper in an axial direction between the annular inclined surface and the pipe.
