Abstract

The device is of the type comprising a connecting bar (16) articulated at one end on one of the elements (10). The said connecting bar is provided at its free end with a transverse groove (20) allowing the attachment of the bar to a male part (22) protruding from the other element (12). On the connecting bar there is fitted a slider (24) having at one of its ends a notch which, when the slider is displaced towards the free end of the bar, engages with the said male part, thus preventing the bar from being raised. The invention is applied in particular to stepladders. <IMAGE>
