Abstract

The invention relates to a connecting device for an electrosurgical instrument, which comprises at least one gas supply line and one power supply line. Said connecting device comprises a housing into which passes the gas supply line including the power supply line disposed therein. The connecting device is also provided with a branching device that is located in the housing, and by way of which the power supply line is diverted out of the gas supply line in order to form a gas-connection end piece and a power-connection end piece, and with a plug fixed to the housing in order to make connection to a socket in an appliance or to connecting leads running to the appliance. The gas-connection end piece and the power-connection end piece are coupled to the plug and a filter is disposed within the housing in the gas-connection end piece.
