Abstract
A telescoping joint for plastic pipe comprises a pair of sleeve members bonded to adjacent ends of a pair of pipe sections, a tubular body member into opposite ends of which sleeve members telescope, with O-ring seals carried by the sleeve members forming a seal against the inner surface of the body member, and tubular adaptor members which fit on the respective pipe sections adjacent the sleeve members and thread into opposite ends of the body member to provide thrust restraint precluding withdrawal of the sleeve members and the pipe sections therefrom. The joint may be used for in situ repairs of fractured pipe, or may be supplied with pipe sections bonded-in, for use in a telescoping joint or union to be coupled into a pipe line.
