摘要： The invention regards a releasable fastening device for an object (40) that in the fastening area for a base (10) is bar-shaped and has a cross section with a round or non-round peripheral shape, e.g. a Christmas tree. When fastening, the object (40) is inserted into an opening (18) between one or several resilient clamping parts (34) that are equipped with e.g. teeth or barbs against the object (40), and further into a centring point (20) at the lower end of the opening (18). The clamping part(s) (34) are rotatably or non-rotatably attached to the periphery of an annular element (28), and each clamping part is preferably rotatable or resilient in the radial direction of the opening (18). In the opening (18), the annular element (28) abuts a preferably circular and horizontal abutment surface (26) in the wall (24) of the opening (18). When releasing, the object (40) is rotated about the longitudinal axis of the opening (18) until the clamping part(s) (34) align with the corresponding recess(es) or enlarged portion(s) (22) of the wall (24). By so doing, the clamping part(s) (34) are released from the object (40) and fall outwards through the recess(es) or the enlarged portion(s) (22), and the object (40) may be removed.
