Abstract

The invention firstly involves a pipe connector (2) having an outer coupling formation and a longitudinal bore from a first end to a second end. The bore is adapted to engage over the end of a pipe (7) at the second end (6) and has a reduced diameter at the first end (5) provided by an inward step (11). A first sealing formation (12) is provided at the first end (5) to establish a seal axially inwardly from the diameter of the bore at the second end. A second sealing formation (15) in the bore establishes a seal about the end of a pipe axially outwardly from the first seal. The sealing formations are annular grooves for elastomeric seals. The coupling formation is preferably a tapered flange (4) for a clamp (3), which will secure two connectors together forming a coupling. Through the configuration of the connectors and arrangement of the sealing formations, a coupling which is pressure assisted is provided. A further feature is that the bore of each connector is screw-threaded (8) adjacent the second end. This enables engagement of corresponding screw-threads (9) on the end of a metal sleeve on a plastics pipe.
