Abstract
A stretching device for stretching of a tire chain, particularly an anti-skid chain. The stretching device comprises a stretching spring, a stretching aggregate for stretching the spring and a stretching element for maintaining an associated tire chain in a stretched position when the spring is stretched. The stretching device eliminates the need for adjusting the tire chain to compensate for slack caused by revolution of the wheels carrying the tire chain.
