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 ).
