Abstract
A heat fusion coupling element 1 comprises: a hollow sleeve member 2 formed from a fusible polymeric material having at least one electrical heating element disposed about its inner and outer surfaces and 3, 4 and electrical terminals 10, 11 mounted on its outer surface, the terminals being connected to the or each electrical heating element and disposed at or adjacent an end of the sleeve member. The element may be used in conjunction with reducing fittings 37, 38 as shown or with one such fitting butt-welded to a pipe end. <IMAGE>
