Abstract
An electrofusion coupling (93) for joining together two or more sections of pipe, said coupling comprising: (i) a substantially cylindrical coupling body having an outer surface and an inner surface, the inner surface being sized and shaped to form a clearance fit with the outer surface of the pipe regions to be joined; (ii) at least one electrical heating (94) element set on or in the inner surface of the coupling body; (iii) terminal means adapted to connect the electrical heating means to an electrical supply; characterized in that the terminal means does not project beyond the outer cylindrical surface of the coupling body once the welding process is complete.
