Abstract
A compression collar is used for reinforcing an interference fit between a piping end and a fitting. The compression collar comprises a reinforcing ring having a tubular geometry with a radially-inward facing surface and a radially-outward facing surface. A sleeve is received around, at least in part, a portion of the radially-outward facing surface of the reinforcing ring and this sleeve wraps around one axial end of the reinforcing ring to form a stop edge thereon.
