Abstract
An apparatus for forming a weld connection with plastic pipe comprises two molded parts and two heating mats. Each part has an internal surface corresponding to a peripheral portion of the pipe being welded such that a cavity for receiving the pipe is defined by the internal surfaces. The parts are separated by longitudinally extending clearances. Each heating mat comprises a plastic coated resistance wire, is associated with one of the molded parts and has one of its end portions in one of the clearances. The mats completely cover the internal surfaces and the pipe periphery being welded.
