A device for stretching foil material and poster holder built with the device includes a guide element and a profile that can be moved and guided crosswise relative to its direction of extension. Two hollow profiles, which are open on their longitudinal sides, extend along the profile with the hollow profiles receiving the edges of the foil material to be stretched. A stretching element is included for stretching the profile crosswise in relation to its direction of extension in any direction in which the hollow profiles are located. The guide element is obliquely mounted on a frame or a structure, so that the profile can be moved or stretched in a transverse direction relative to the direction of extension and obliquely relative to the direction of stretching of the foil material which is to be stretched. The poster holder has at least one such device, which is mounted on a free-standing frame, or forms such a frame, or is mounted on a structure. The stretching profile can be moved and stretched transversal direction relative to its direction of extension and obliquely relative to the direction of stretching of the foil material that is to be stretched. The stretching forces are received solely by the device.
