Abstract
Abstract A connecting element for a glass sheet of multi-pane glass, in particular of laminated glass, which incorporates at least an outer pane, an inner pane and a laminating element joining the panes to one another, as well as an electrical arrangement located between the panes, the connecting element incorporating at least a metal foil strip being at least partly insulated, being connectable to the electrical arrangement and bondable to the outside of the inner pane. To make it possible that the connection to the electrical arrangement can already take place prior to the laminating process and to provide assurance for the connecting element against peeling off during manipulation of the finished glass sheet the inner section of the metal foil strip connectable to the electrical arrangement extends between the inner pane and the outer pane. The outer section of the metal foil strip bondable to the outside of the inner pane incorporates an area with a greater thickness than that of the inner section and forms a single piece with the inner section. At least on fold location is provided between the outer section and the inner section in the region of the edges of the inner pane.
