Each movable jaw is multi-layered and includes a pair of movable, pivotable clamping claws spaced vertically of one another. Said clamping claws are each provided with forward multi-faceted portions including at least a pair of planar clamping faces arranged transversely of one another. A non-movable supporting ring member is interposed between the pair of clamping claws. This support member has a forward portion extending substantially inwardly of the multi-faceted planar faces of the respective movable clamping claws. The support member further has a rearward portion provided with a flat edge for bearing against an upwardly-extending base member.
