ABSTRACT:
A manually operated tool adapted to crimp a sheet metal clasp around overlapped lengths of non-metallic strap. The tool is operated by manually pressing together a pair of handles. A first portion of such handle movement pivots opposed die members from an open position at which opposed ledges on projecting ends of the die members are spaced apart to afford positioning the die members on opposite sides of the clasp, to a closed position at which the projecting ledges are closely adjacent to essentially encircle the clasp within a passageway defined by the die members and a plunger between the die members. A second portion of such handle movement maintains the die members in their closed position and drives the plunger toward the ledges to crimp the clasp against a die surface defined on the ledges.
