 are to be brought into connection.



   Up to now it has been customary to provide the handles, legs, etc. of such tools with special contact and connection elements for the electrical connection lines in such a way that the handle and line and their insulation represent parts of their own. and therefore always had to be brought into a fixed relationship required for the practical handling of the tool.

   At this point, the isolation was mostly unreliable.

 measures were partly inadequate. sometimes too cumbersome.



   According to the invention, the insulation of the line cord and that of the tool handle are designed appropriately so that the line cord has the highest mechanical loading

   According to the invention, the insulating sheath of the cord is lengthened and formed in this way to achieve this goal. that it also surrounds the current-carrying leg of the tool handle and also surrounds the contact element (plug, connection eyelets) at the other end in an insulating manner.

   The insulation of all current-carrying parts is then a uniform, homogeneous whole and consists of a common rubber jacket, which is molded or molded. Pressing process is produced coherently in one continuous operation. u. between

   however heavy these demands may be. sensitive and disadvantageous damage to the insulating sleeve. There are also conductive parts, namely the handle. for the purpose of an unconditional tight fit of the rubber jacket with notches. like billen and grooves, as well as burden. which have to act as an abutment.



   In the drawing, the invention is illustrated in one embodiment. u is the current-carrying handle of a pair of pliers. b the current-carrying single core, c the insulated connecting cable, the common rubber jacket.
