A mounting for a grinding wheel serves to connect the grinding wheel to the tool spindle of a grinding machine has a holding member for the grinding wheel and a threaded fastener which separably secures the holding member to the spindle. The fastener is surrounded by an annular retaining portion of a tensioning device which has elastic prongs at one side and a compression spring at the other side of the retaining portion. The prongs are clamped between the holding member and the head of the fastener in response to rotation of the fastener in a direction to couple the holding member to the spindle, and the compression spring then reacts against the spindle so that the tensioning device maintains the fastener in form- and force-locking engagement with the holding device.
