Abstract: A releasable fastening device that includes a rivet (3) that can be inserted in through openings (5, 6) of components (1, 2) that are to be mounted. The rivet (3) is provided with a projection at one end and with spreadable expansion elements (4) at its other end. A threaded bolt (8) is axially pushed into an internal counter-thread of the rivet (3) to spread the expansion elements (4). When the fastening device is assembled, the walls of the components (1, 2) or of an intermediate element (7) engage radial recesses on the circumference of the rivet (3) to hold the components securely. Bolt (8) can be unscrewed from the rivet (3) to facilitate disassembly.
