Abstract: In a system made from an edge trim strip and a bridging component for the bridging, especially in optical manner, of a structural transition between the edge trim strip and the bridging component, a simple and secure connection of the edge trim strip and the bridging component should be made possible with the simplest possible fabrication and design of the edge trim strip. The securing of the bridging component to the edge trim strip is accomplished solely by a fastening leg provided on the edge strip and forming an undercut, and the fastening leg is the sole leg of the cross section profile of the edge trim strip serving to secure the bridging component. The bridging component has a locking means in the form of a locking groove, which is able to engage at top and bottom with the fastening leg provided with the undercut in a locking manner.
