The device has an insulating case traversed by a battery ground cable (2) that is cut. A contact stud (3) is welded at each cut end of the cable to assure contact with the ground of a motor vehicle battery. The studs support on an adjustable core (4) of an electromagnet (6) via presser springs. The electromagnet coil is tensioned to sink the core to release the studs from the cable. Two rods (11) are mounted on springs (12) in the case.
