ABSTRACT:
An automobile-tire snow chain comprises running chain sections connected between a closed outer annular maintaining chain and an open inner maintaining chain. A long chain section is connected at one end to a first ring on one end of the inner chain and is looped through a second ring on the other end of the inner chain and through the first ring, so that the inner chain can be closed by pulling on the long chain section to tighten the loop. This long chain section includes a running chain portion which passes over the tire and is secured to a buckle on the outer annular chain, the free end of the long chain section being threaded about the outer annular chain and secured by a tensioning spring and a buckle.
