Improved leaf retaining device, characterized essentially by the fact of comprising two elongated wings longitudinally associated in an articulated manner to form a dihedral of variable angle according to two stable positions corresponding to those of joining or separation of the ends of pins that they project normally from the free edges of said wings, because said wings are retained by their outer edges at the turned edges of a rigid profile of section convex to the outside; because the articulated edges of the wings are provided overlapped by areas, between which punched portions of edge that act as a stop are constituted, and in that the means for the movement of the wings are constituted by pushbutton parts located at the ends of the wings. Wings and provided with a pusher appendage thereof to the position of opening or separation of the lugs. 2d sheet retaining device perfected.
