Abstract

A device for connecting components (1, 2, 3) made of fusible plastic, especially pipes (12, 60) of a fuel pipeline or a fuel line to a fuel tank (8) of a vehicle. The device includes a heating element (4) having ends (44, 46) which are used to supply electrical energy. The device is easy to use, simple to mount, and produces a functionally reliable welded joint between the components (1, 2, 3). To achieve this, one component (3) includes a retaining body (16) for a retaining tool (50), and the two ends (44, 46) of the heating element (4) extend onto the retaining body (16) where they can engage contact elements (56, 57) on the retaining tool (50).
