Abstract

Safety device against undue release of a screw with head, the head of which is arranged in a cavity that loosely surrounds the head, characterized in that a ring with a smaller external diameter is located under the head of the screw with a head, than that of the head, and because on the head and in the intermediate space between it and the cavity is fitted a safety cap that is locked in its mounting situation.
