Abstract: A first jaw is rigidly mounted to a handle. A second jaw is pivotally mounted to a portion of the first jaw adjacent the portion to which the handle is secured. A spring biases second jaw member toward a closed position with respect to the first jaw. A crimping force application assembly is rotatably attached to the second jaw using a bushing which rotatably receives a second end of a longitudinally extending rod of the assembly. A second end of the rod is threadedly received in a spindle. The spindle has first and second pintles which can be seated in slots in the upper surface of the first jaw. The rod can be rotated using a manually actuated member or a second member which can be engaged by a power tool or hand tool to draw the first jaw engaged by the spindle toward the second jaw which is attached to the bushing applying a crimping force to a compression sleeve to affix it to a portion of plastic pipe.
