The invention relates to a device (2) for conducting an electric current (5) on a current path (6) between an electric connection cable (42) connected to a vehicle battery and the vehicle battery. The current path (6) is divided by an electric interruption (8) into two current path parts (10, 12) which are electrically interconnected by means of a current sensor (18). Said claimed device (2) comprises a mechanical connection element (4, 38) for mechanically connecting the vehicle battery and the connection cable (42), and an electric connection element (24, 26) which is different from the mechanical connection element (4, 38) for electrically connecting the current sensor (18) to one of the current paths (10, 12).
