  • the invention proposes that the spreading elements have at least one receptacle for a workpiece. If the spreading elements are replaceable, for example, connected to the spreading jaws, different spreading elements can be used with the same pliers to produce different connections. Thus, a set used by a craftsman set may have a pair of pliers with several different spreading elements. It is also possible that a spreading element includes several different shots. Also in this case can find several replaceable spreading elements, each with multiple recordings, use.
