Abstract: A band tightening and securing tool has a rigid slide frame with parallel side slide rails connected at their forward ends by a transverse nose end portion flattened in the plane of the frame and at their rearward ends by a crossbar portion. A cross slide member bridging and slidable along the slide rails has a clamp arm mounted at one end on the cross slide between the slide rails and carrying at its other end a clamp device aligned with the longitudinal center line of the frame for tightly gripping and holding the free end portion of the band in a position extending lengthwise of the frame medially between its slide rails and flatwise across the flattened nose end of the frame.
