ends of each circumferential chain are mating detent clasps 20 22 configured to be fixed to each other when the chain is placed around the wheel in order to maintain the chain on the wheel extending between each circumferential chain 14 and attached thereto is a plurality of cross chains 18 which are ordinarily configured to provide the snow chain with traction when it is used in snow the cross chains 18 typically extend parallel to each other and are perpendicular to the circumferential chains 14 so that a maximum amount of traction may be imparted to the wheel when the snow chain is used in its intended manner fig2 exemplifies the structure 10 of an embodiment of the invention attached to a vehicle wheel added to the chain 12 are features which provide the invention with its novel and useful properties with reference to fig1 and 2 there is exemplified how at least one mirror image of a mark may be attached to the chain 12 in this regard a rectangular plate 30 may be formed to carry the mirror image of the mark and the plate may be attached to the snow chain by using at least one of the cross chains 18 to form a base for attachment as exemplified in fig3 in some embodiments the plate 30 may comprise two platelets an upper platelet 32 and a lower platelet 34 which are configured to be joined or fused to each other and to capture portions of the cross chains 18 which are sandwiched between the platelets fusion of the.
