According to the invention, this safety device for a mechanical element with non-horizontal displacement controlled by a screw/nut system comprises in combination – a safety nut in two parts, an inner and an outer, with matched frustoconical surfaces and a housing which is fastened to this mechanical element and through which the control screw passes and which encloses the safety nut in such a way as to be temporarily connected to the inner part in terms of rotation and to be capable of bearing on the outer part when the supporting nut fractures. The invention is particularly intended for the vertical adjustment of the loaders and extractors of drawing presses for automation installations on presses.
