Abstract
A protective tire chain having a running section and lateral sections which comprise at least one tensioning device for tensioning the tire chain. The tensioning device is by means of two link members linked to links of the tire chain. These two link members are continuously spring urged toward each other so that the tensioning device continuously tends to assume its shortest overall length and consequently to tighten the chain. The two link members are, however, also movable away from each other against the spring thrust into a position in which the tensioning device has its maximum overall length or at least a considerably greater length than its shortest possible length. The tensioning device is provided with an unlatchable locking device which is operable selectively to lock the tensioning device in its maximum or longer length position to facilitate the mounting of the tensioning device.
