A device for incorporating identification codes into glass surfaces, in particular glass surfaces of motor vehicles, to prevent theft in motor vehicles consists of the following: a template film (20) made of material resistant to etching paste which has an adhesive coating on its rear surface (20a) and contains the code (10) in the form of punched perforations (11); a backing film (30); a protective sheet of oil paper covering the adhesive coating (25); and an application film (40) which is held to the top surface (20b) of the template film (20) by an adhesive coating (45) and which serves to hold and fix the areas (28) of the template film (20) which remain after island-shaped perforations (11) for the code (10) are punched out of the template film (20). The adhesion of the adhesive layer (25) to a glass surface is greater than the adhesion of the adhesive layer (45) to the template film (20). |
