The plates have channels on their peripheries, and are mounted on components with slots. The fastening has a tube element engaging the plate etc. (10). The fastening can be fastened inside the peripheral channel (21) and has a hook-shaped part projecting from the channel and engaging the slot (20). It has further a curved, cam-like surface adjacent to the channel outer edge, and at a distance from it. Thus engagement between the hook-shaped part and one of the slots in the element (12) presses the tube element and the plate toward each other.
