A tool for simultaneously inserting each of a plurality of wires in respective non-deforming insulation piercing terminals disposed in a terminal retaining body. The terminal retaining body is supported in the tool so that each terminal is aligned with a guide slot through which the wires are forced by the action of insertion tabs. The ends of the wires are retained in coil springs which are coupled to releasing handles so that the springs may be extended to facilitate removal of the wires. As the insertion tabs are forced through the guide slots, a cutting member disposed in each of the slots cooperates with an edge of the insertion tabs to cut the wire at a predetermined point. The tool is adjustable to accept terminal retaining bodies of various shapes and sizes.

A contact element of an electric connector to be mated with a flat flexible film circuit board. The contact element affords a good electrical connection and also easy disengagement of the circuit board by providing a semi-conical projection on the end of its spring portion and by providing a slant surface from the conical projection to an end of the spring portion.
