In order to provide possibilities for considerably simplifying the identification of products on a device for retaining product identification labels, easy recognition of the labels also being desirable, a dimensionally stable support is provided with at least one window-like perforation (3) arranged in front of a light source, and the perforation (3) has a diffusion screen (6) extending over its entire surface, in front of which is exchangeably mounted at least one transparency (7) on which the product and at least one symbol assigned thereto are displayed. <IMAGE>
