ABSTRACT:
A fitting for forming a sealed joint with a plain end portion of pipe includes a semi-elastic sleeve member having enlarged ends with annular sealing gaskets received therein. An inwardly extended ridge member is circumferentially arranged at the longitudinal midportion of the sleeve member and provides an abutment surface for limiting the inward extension of a pipe end. A plurality of circumferentially spaced rib-shaped protuberances are positioned within the sleeve member and extend radially inwardly from the interior surface for compressibly gripping and supportably engaging the pipe end within the sleeve member.
