A device for holding a credit card purchase form is shown and includes a generally planar base having a flat surface portion over which the form extends. A clamp member is provided, the clamp member having one edge adapted to engage the edge of the form and to force it against the base member. The clamp member pivots on its other edge. A pair of spaced apertures are formed in the planar base and a pair of hinge members project from the pivot edge of the clamp member and extend through the spaced apertures and provide a hinge arrangement for the clamp member. A lever member is fixedly joined to the pivot edge of the clamp member, and the lever member includes an end movable toward the planar base to cause pivotal movement of the clamp member and movement of the clamping edge away from the base. A compression spring is provided for biasing the lever member away from the base and for thereby biasing the clamping edge into clamping engagement with the base member, one of the ends of the spring engaging the lever member and an opposite end being supported by the base.
