ABSTRACT OF THE DISCLOSURE A pair of elongated clamp levers are provided and interconnected intermediate their opposite ends for substantially coplanar relative oscillation of the levers to inversely swing corresponding pairs of ends of the levers toward and away from each other. One pair of ends defines opposing jaw ends between which a sheet metal marginal portion may be clamped and a wedge assembly is movably connected between the other pair of ends of the levers and includes operating structure movable lengthwise of the levers and to which one end of an elongated pull member may be anchored. The wedge assembly, when the operating structure is displaced away from the jaw ends of the levers, is operative to spread the other pair of ends of the levers apart, the operating structure being effective to apply a high wedging force-to- pull force ratio during initial movement of said operating structure away from the jaw ends of said levers and to progressively diminish the aforementioned ratio as the operating structure is displaced further away from the jaw ends of the levers.
