The anchoring plate is provided with a plurality of openings each of which includes a ridge or bulge portion projecting from the surface of the anchoring plate which faces the support surface for the ramp ends to form a claw-like structure for firmly gripping the support surface. A layer of material may be provided between the upper surface of the anchoring plate and a lower surface of the ramp end to increase the friction between the anchoring plate and ramp end.
