Abstract

Device that allows to prevent the deregulation of facilities accessible to the public equipped with control devices of which a shaft supports a regulation disc, characterized by a clamp element consisting of a piece of folded U-shaped sheet metal of which the two branches of the U each have a non-circular perforation in the vicinity of the curved part of the U, by a clamping device held by the two branches of the clamp element, by a suspension stem or tongue of non-circular section, less than the non-circular section of the perforations of the clamp element fitted in said perforations, this stem or tongue being oriented parallel to the shaft that supports the regulation disc and fixed in such a way that the periphery of the regulation disc is located between the ends of the branches of the clamp element.
