Abstract

In an adhesive connection between the marginal area of an auto glass pane (1) and the emplacement flange (2) of the window frame of an auto body, a completely enclosed hollow space (8) is provided in the adhesive bead (4) which provides the connection by, e.g., having a hose (7) made of elastic synthetic material embedded in the adhesive bead (4). The hollow space (8)serves as an aid in window removal by being filled with compressed air with the aid of a hollow needle (9). In this way, the elastically or plastically distortable adhesive bead (4) is expanded, and the glass pane is pushed out of the window-frame (3) sufficiently that the separation of the adhesive bead (4) is considerably facilitated.
