A connector system and associated connecting method in the system including a plurality of sets of connectors (1), each set comprising or including a tubular connector fitting (2) and respective pipe-end spigot(s) (3), each spigot having a first end (4) for fitting into and supporting the end of a pipe (5) and a second end (6) for fitting into a correspondingly shaped bore (7) in the connector fitting, an '&Ogr;' ring seal (12) within the connector for sealing the outside of the pipe end spigot and/or the pipe, the first end of the spigot including one or more continuous teeth (9) for gripping and sealing the inside of the pipe end, a radially expandable split collar (11) having an outer taper corresponding to a correspondingly shaped tapered chamber (10) in the connector fitting whereby upon positive pressure being applied from the inside of the pipe tending to force the pipe out of the connector the tapered collar slides towards the narrower end of the tapered chamber to thereby grip the pipe end and hence the toothed first end of the spigot to thereby collectively prevent or inhibit the pipe end from delaminating as a consequence of water ingress due to high internal water pressure. |
