ABSTRACT:
A portable hand tool for crimping ferrules on flexible conduits such as are used for electrical wiring, for example. Two members pivotally connected to each other have handle portions for manipulation by the user, and jaw portions. One jaw portion has a fixture pivotally mounted on it, for receiving a ferrule which has been placed on but not yet crimped to the end of a conduit. The other jaw portion has laterally spaced arms which straddle the conduit and, as the jaws move toward each other, exert pressure on the usual nut which serves also as a crimping member, to force the internal crimping flange of the nut axially against the rear end of the ferrule to deform the metal of the ferrule and crimp it firmly onto the conduit.
