(54) Cover plate


(57) A cover plate (1) according to the invention comprises a groove (5, 8, 9) arranged on the surface of the mounting cover that is to be fitted against the mounting base. The groove forms a loop so that it encircles the machined opening when the cover plate is fitted on the mounting base. There is a neck of material (7) between the bottom of the groove (5, 8, 9) and the front face of the cover plate. If an attempt is made to pry the cover plate off the mounting base by inserting a tool such as a chisel between the mounting base and the edge of the cover plate, the neck of material between the bottom of the groove and the cover plate will give way, making the outer edge of the cover plate separate from the rest of the cover plate structure. The remaining cover plate structure does not provide any good support surface.
