Stand for clamping post- or pole-like parts, in particular Christmas trees, wherein the stand has the following features: - at least two retaining elements are connected to a receiving device for receiving the post-or pole-like part and arranged offset around a central axis of a receiving compartment of the receiving device and can each be pivoted about a horizontal pivot axis or about a pivot axis with a horizontal component away from the central axis in the direction of a release position or open position and towards the central axis in the direction of a fixing position; - the receiving device is mounted with a variable spacing from a baseplate of the stand; - the receiving device is connected to at least one coupling device which is coupled in movement to a tensioning device (40, 42); - the tensioning device (40, 42) is connected to a flexible tensioning cable (81, 82) or to a plurality of flexible tensioning cables (81, 82) which is/are respectively coupled to a retaining element or to a plurality of retaining elements; - by reducing the spacing between the receiving device and the baseplate, the receiving device drives the tensioning device (40, 42) via the coupling device in such a way that the flexible tensioning cable (81, 82) or the flexible tensioning cables (81, 82) is/are pulled and/or forcibly urged in a pulling direction by the tensioning device (40, 42) such that the tensioning device (40, 42), by way of the flexible tensioning cable (81, 82) or by way of the flexible tensioning cables (81, 82), counteracts or prevents pivoting of the retaining element or the retaining elements away from the central axis in the release position direction. - at least two retaining elements are connected to a receiving device for receiving the post-or pole-like part and arranged offset around a central axis of a receiving compartment of the receiving device and can each be pivoted about a horizontal pivot axis or about a pivot axis with a horizontal component away from the central axis in the direction of a release position or open position and towards the central axis in the direction of a fixing position; - the receiving device is mounted with a variable spacing from a baseplate of the stand; - the receiving device is connected to at least one coupling device which is coupled in movement to a tensioning device (40, 42); - the tensioning device (40, 42) is connected to a flexible tensioning cable (81, 82) or to a plurality of flexible tensioning cables (81, 82) which is/are respectively coupled to a retaining element or to a plurality of retaining elements; - by reducing the spacing between the receiving device and the baseplate, the receiving device drives the tensioning device (40, 42) via the coupling device in such a way that the flexible tensioning cable (81, 82) or the flexible tensioning cables (81, 82) is/are pulled and/or forcibly urged in a pulling direction by the tensioning device (40, 42) such that the tensioning device (40, 42), by way of the flexible tensioning cable (81, 82) or by way of the flexible tensioning cables (81, 82), counteracts or prevents pivoting of the retaining element or the retaining elements away from the central axis in the release position direction.
