The invention (1) is used to connect a line element (2) to a component (3). The line element (2) ends in a connection housing (5) or is connected to such a housing in a fixed manner. Means lie between the connection housing (5) and the component (3) for removably fixing (7, 13). A line portion (9) that runs in the connection housing (5) is heated by an electric heating wire (10). The heating wire (10) surrounds the line portion (9) from the outside. The heated line portion (9) protrudes in the direction of the component (3) beyond the region for removably fixing the connection housing (5) to the component (3) to such an extent that said line portion ends in the interior of the component (3).
