Abstract

A wheel chain has a running lattice structure which is tightened by a pressure cord (8). The pressure cord (8) is connected to a lateral lattice structure arranged on the outer side of the vehicle tires by connecting members (6). Each of the connecting members has a connecting loop (10) for a member of the lateral lattice structure, and a guiding ring (9) for the pressure cord (8). In order to preserve an excess length (7) of the pressure cord (8), the cross-section of the connecting loop (10) is sufficiently large so that the connecting loop (10) provides a pull-through conduit for the excess length (7) of the pressure cord (8).
