An anti-theft device ( 10 ) for portable computers having a base casing ( 12 ) and a hingeable cover ( 14 ). One wall of the base casing ( 14 ) is formed with a dedicated slot ( 16 ). The device ( 10 ) is generally U-shaped, having two legs ( 20; 22 ), and a web portion ( 24 ). The device ( 10 ) comprises a rotatable locking mechanism ( 26 ) installed within the web portion ( 24 ), drivingly coupled to a T-shaped tip ( 28 ) adapted to be inserted into the slot ( 16 ) in one position of the mechanism and, by rotating the mechanism by less than 180°, the tip ( 28 ) becomes locked within the base casing ( 12 ) while the legs ( 20; 22 ) extend one ( 22 ) underlying the bottom surface of the base casing ( 12 ) and the other ( 20 ) overlying the top surface of the hingeable cover ( 14 ), thus preventing the opening of the cover. A cable is used for securing the device ( 10 ) to a stationary object ( 32 ).
