Abstract: The plastic holder for two credit cards in accordance with the invention has eliminated the drawbacks of known card holders with such a design solution that makes possible the production of a jacket (1) in which there is space for two credit cards (A, B) and that is easy to produce by spraying, because of an intermediate rib (2) which runs along the middle of the inner side of the lateral walls and the end wall, and which thus represents a guide for individual card (A, B) in the holder and does not damage its surface and/or magnetic tape (C), and in addition, provides support during the spraying procedure, so that no other holding elements need to be added. Inside the holder, additional protrusions (5) or (6, 6') are carried out, which slightly bend individual card. At the inner sides of the upper plane (1') and the lower plane (1") of the jacket (1) additional protrusions (3, 3') are carried out, so that the planes (1, 1") of the plastic jacket (1) have a slightly concave shape.
