Abstract

A window pane (1), in particular an automobile window pane, is adhesively bonded to a frame (8) of a window opening by an adhesive bead (6), and carries a profiled bead (3) provided with a recess (4) extending longitudinally and a tear-away cord (8) laid therein. Tear-away cord (8) is designed for breaking the adhesive bond between window pane (1) and frame (7). A contact surface is provided for adhesive bead (6) alongside profiled bead (3). In the fitted state, recess (4) is open toward adhesive bead (6) so that the tear-away cord may be pulled without exerting a high force directly in the adhesive bead that abuts the opening of the recess.
