Arrangement for mounting an electrical unit in a vehicle

The electronic security unit (28) is fitted into a housing (52) included in the intermediate fixing fitting which supports the vehicle battery on the chassis (22,14). A U shaped member (51) made from an elastic metal such as spring steel grips the electronic security unit and protects the connections (57) from interference. It is secured by ears which are screwed (64) to the intermediate fitting walls (38,40)
