A third stiffener (40) is longitudinally mounted between two lower beams (26) of the box, where the stiffeners (36, 40) are made of plastic, steel and aluminum. The upper and lower beams are respectively arranged between upper and lower corners of lateral flanks (22) of the box. Upper and lower card guides (28, 30) are fixed on the upper and lower beams of the box, respectively. An independent claim is also included for a box for receiving an electronic card.
