The intruder-proof action is to be improved and the production costs reduced. A sheet of laminated safety glass (14) is arranged at a distance behind the first sheet (10), which is from 6 to 20 mm thick. In this laminated sheet, individual glass sheets (16, 18, 20) are bonded to one another by multilayer plastic films (22, 24) at least 1 mm thick; the sheet facing the gap (12) between the sheets is at least 5 mm thick; the other sheets have a thickness which decreases in steps on moving towards the sheet (16) facing away from the gap. <IMAGE> |
