A theft protection for an electronic device, in particular an optionally portable computer, a mobile telephone or a PDA, comprises an electrical cable (2) with a coupling connector (3) for coupling to a corresponding coupling connector of the device. Alarm means are connected to the cable (2) which are able and adapted to generate an alarm signal in the case the device is stolen. The alarm means (4) are accommodated in a housing (1) separate from the device. The housing is provided with fastening means (5) for a mechanical connection of the housing to a fixed object (9). The alarm means comprise detection means which are adapted and able to detect an interruption of the electrical cable connection (2), in addition to signalling means (4) which generate the alarm signal when said interruption is detected.
