Abstract
A locking device includes a housing or a casing (3) having an opening (8) for the insertion of a lock activating card (6). The locking device includes a cylinder lock (5) which actuates a catch hook, an intermediate member (2) which is connected to the catch hook through the medium of a latch pin (10), and a pin-like latch member (1) that restricts movement of the intermediate member and therewith also movement of the catch hook until a correct card (6) is inserted into the opening. The card (6) includes at least one hole (6a) and the latch pin (1) can move perpendicularly to the card and therewith be received in the hole in said card, wherewith the latching effect of the latch pin is cancelled and the intermediate member is free to move. The latch pin (1), and therewith the card, is held fixed when the catch hook is swung out.
