Abstract: The invention relates to a clamp holder for attaching a display means to a base. The clamp holder comprises a holding element. The holding element is provided at one end with a first clamp member for fitting the display means and at a second end with a second clamp member for attaching the holding element to the base. The clamp members are spaced apart from each other by a fixed member. The first clamp member defines a first clamp plane, which is offset by an angle (?) to a second clamp plane defined by the second clamp member.
