In the use of dumbbells, which are widely used for physical fitness, in order to enable the dumbbell discs, which are replaceably arranged on the dumbbell bar, to be secured more rapidly and with less effort, clamping elements (3) are mounted in a housing (1) on a fulcrum (6) and can be firmly clamped on the dumbbell bar (7) by means of a spreading and securing piece (2), and subsequently released again. A spring (5) contributes to the guiding of the clamping elements (3), which are provided with a rubber coating (4) so that the dumbbell bar (7) is not damaged. <IMAGE>
