An anti-theft alarm device for portable articles is disclosed. The device comprises a motion sensing component for sensing movement of the device and for generating an alarm actuating signal in response to such movement. A conductive tether is attached to the device and extends around the article, holding the article in a predetermined position in relation to the device, and for generating an alarm activating signal upon disconnection of the cable to permit movement of the article from a predetermined position. A microprocessor is provided to receive alarm activating signals from the motion sensing component and the conductive tether, and to receive input signals entered by digital code entering means connected to the microprocessor.
