A tensioning device, for drive belts (5), which is formed by a resilient bendable ring (8). The ring is arranged to be inserted between lengths of the drive belt and may be positioned in a groove (9) in one of the pulleys of the belt transmission of which the drive belt is an integral part. The ring is designed with such a large circumference that during expansion it is squeezed between the lengths of the drive belt, which causes a tensioning thereof. |
