The tensioning and fastening apparatus includes a driving assembly, a tensioning assembly, a pair of wrapping band holders, an electrode plunger, and a movable plate assembly. The movable plate assembly preferably includes an upper plate and a lower plate which are slidable relative to one another so as to expose a counter electrode mounted on the lower plate when fastening or welding of the looped band is desired. The movable plate assembly is also preferably mounted for reciprocal movement relative to the frame of the apparatus to enable removal of the welded band loop.
