The clamp has two interacting clamp elements (14) which can be moved relative to one another. These are intended for retaining a sheet-like article (70). The clamp (12) also has a holding-open element (20) which is intended for engaging between two parts (78, 78') of the article and, when the clamp elements (14) are located in the closed position (18'), for keeping these parts (78, 78') separate from one another and thus holding the article (70) open. |
