The plate has a body with a series of holes, at its lower part, for suspending metallic chains. A flange is present in a central part of one side of the plate. The flange separates plates when the plates come together during their movement, while preventing the chains from entangling. A central upper part of the plate is extended into a head. A base (15) and a cover (16) of a clamp constitute a space to surround the head with a clip of collets.
