The joint includes a gland having a conical cavity for receiving a toothed split ring that coaxially compresses and grips the plain pipe end as the gland is tightened to the bell. The joint is sealed by a compressible gasket positioned between the split ring and the bell. The gland further includes an integrally formed, radially extending shelf for abutting against the split ring and mechanically stopping the gland from being pulled over the split ring during joint assembly.
