An electrofusion coupling for joining together two or more sections of pipe or for joining a section of pipe and a pipework fitting, said coupling comprising: (i) a first part () having a first internal diameter at a first end adapted to form a tight sliding fit with a first pipe section and a second internal diameter at a second end, larger than the first; (ii) a second part () having a first internal diameter at a first end adapted to form a tight sliding fit with a second pipe section and an outside diameter at a second end adapted to form a tight sliding fit with the second internal diameter of the first part such that the two parts can nest together tightly with an overlapping region; (iii) electrical heating elements () and electrical terminal connections being provided in the two parts such that the first part can be used independently of the second part to join a section of pipe to a pipework fitting or the first and second parts can be used in combination to join two adjacent sections of pipe.
