Abstract: The invention relates to a device for keeping cards, said device being provided with at least one card holder in which a card can be held at at least some of its edges, while the card holder is rotatably connected with lids located above and under the card holder. The card holder is provided with four legs bounding a rectangular through opening the size of a card to be accommodated, the legs forming a closed frame with external dimensions at least substantially equal to the external dimensions of a lid. The legs are provided with parts projecting into the opening, such that a card inserted into the opening is enclosed between at least one pair of projecting parts forming part of two opposed legs, said parts butting against the upper surface of the card, and at least one pair of projecting parts, which also form part of two opposed legs and which butt against the lower surface of the card.
