Abstract

The device (1) is in the form of an approximately U-shaped electrically conductive contact part. Inserting the cable (L) into the cable insertion arm causes the arms (1A,1B) of the clamping part to be spread by the insulation. The blades (1A1,1B1) are correspondingly spread and cut through or cut off the insulation during further insertion of the cable and contact the cable core under the pressure generated by the spreading effect.
