ABSTRACT:
A Connector for corrugated pipes or rods comprises a housing (2) having an open end (3) for insertion of a pipe or rod into a bore (5). A pair of resilient locking members of fingers (9) are formed in the housing wall and include projections (10) which extend into the bore (5). The projections are so shaped as to lock into a single valley of the pipe or rod corrugations to prevent withdrawal of the pipe or rod. Also disclosed are methods of moulding the connector in which the fingers (9) are held and/or forced outwardly from the mould during withdrawal of a central core which forms the bore (5) to avoid damage of the fingers by the core.
