ABSTRACT:
A split-ring for use in a pipe coupling comprises an outer conical surface defined by the top lands of a plurality of spaced axially-extending ribs formed on its outer surface. Also described is a pipe coupling comprising a housing for receiving one end of the pipe, the split-ring, and a sleeve formed with an internal conical surface engagable with the outer conical ribs of the split ring to cause the ring to tightly clamp the pipe within the housing. In one described embodiment, the split-ring is constituted of a single unit formed with an axially-extending slit; and in a second described embodiment, it is constituted of two hinged sections.
