The present invention relates to a connecting device and to a monopolar cable for surgical instruments operable in a monopolar and bipolar manner, especially for high-frequency surgery, and a corresponding surgical instrument and surgical system. An electrical terminal of the connecting device is designed to be connectable either to a monopolar cable for monopolar operation or to a bipolar cable for bipolar operation. A first contact and a second contact of the electrical terminal are electrically connected to an accessory coupling of the connecting device and are designed with insulation such that an accessory coupled by the accessory coupling is operable either in a monopolar or bipolar manner via the two contacts. The present invention further relates to a monopolar cable for such a connecting device, to a surgical instrument comprising such a connecting device and to a surgical system comprising such a surgical instrument and such a monopolar cable.
