Abstract: A belt drive comprises a first pulley and at least one additional pulley and uses an elastic belt that is engagable over the pulleys. An auxiliary unit, connected to the first pulley, has a detent. A tensioning link comprises an open-ended slot for receiving in a slidable manner the detent. In an operating position of the belt drive the detent is locatable at a closed end of the open-ended slot and to obtain a belt changing position the detent is movable along the open-ended slot towards an open end of the open-ended slot. Movement of the detent along the open-ended slot requires simultaneous rotation of the auxiliary unit,
