Patent ID: 7174607

Claim:
A card attachment comprising: a first jaw and a separately formed second jaw, the first jaw being pivotally connected to the second jaw such that the first and second jaws can be moved between an open position in which the first and second jaws are spaced apart and a locked closed position in which the first and second jaws are pressed into abutment without overlap; the first jaw comprising a biasing member that extends along the second jaw, the biasing member comprising a first gripping surface, the second jaw comprising a second gripping surface that opposes the first gripping surface, the first and second gripping surfaces extending in generally parallel planes when the first and second jaws are in the closed position; the second jaw comprising a base with a first side wall and a second side wall extending upward from the base, the first and second side walls being laterally spaced by a distance less than a width of a widest portion of the biasing member, the first and second side walls being positioned between a first end of the biasing member and an opposite second end of the biasing member, the first and second gripping surfaces terminating at a first distance from a distal end of the second jaw and a distal surface of each of the first and second side wall being positioned at the first distance from the distal end of the second jaw; a lever having a generally L-shaped configuration that defines a cam portion and a lever arm portion, a pivot pin pivotally connecting the lever to the first and second side walls such that the lever is not capable of substantial translation relative to the first and second side walls, the pivot pin extending through the cam portion of the lever, and the cam portion being adapted to contact the first jaw when the lever is pivoted to a position such that the lever arm portion is substantially parallel to the first jaw.
