1. A neutral electrode useful during high-frequency surgery for conducting a high-frequency surgical current from a patient, comprising:
- an electrode split into at least first and second flat partial electrodes;
an insulating strip separating said partial electrodes from one another; and
an electrical resistance placed between said partial electrodes and in electrically conductive contact with each of said partial electrodes, wherein each said partial electrode has an electrically conducting protrusion making contact with said resistance, each protrusion, as viewed from the side, is bent into a "U"-shape, and at least a portion of said resistance is placed within the interior space of each of said "U"-shaped protrusions, thereby making forced contact with said protrusions.

Abstract
A split neutral electrode useful for electronic surgery, consists of at least a first and a second partial electrode separated from each other by an insulating strip. An electrical resistance establishes an electrical connection between the partial electrodes. Each partial electrode preferably has a protrusion which is wrapped around and makes forced contact with the resistance. An associated terminal clamp constructed in the form of an alligator clip contains two metal overlays which are brought into contact with the protrusions upon closure of the clamp.
