Abstract: For replacement of a rear window pan (2), which has become unusable, in the folding hood (1) of a convertible a replacement pane (6) is provided of which the encircling frame (7) is provided at its inner side with a hot-melt adhesive (9). Worked into the encircling frame (7) are electrical resistance heating wires (10) which can be subjected to current to soften the hot-melt adhesive (9) to enter an adhesive bond with a remaining edge region (5) of the old pane (2). Another pane replacement can be carried out simply in that the hot-melt adhesive (9) is again softened, the fitted replacement pane removed and replaced by a new one of the same type.
