ABSTRACT:
A connecting spike (16, 17, 18) is used for flexibly interconnecting two chain links (1, 2) of a track, specifically for tanks. The spike comprises a metal bolt (8) with a vulcanized-on rubber sheathing (13). On inserting spike (16) into bores (5) of chain links (1, 2), it is elastically deformed. Sheathing (13) is one-part developed and has thicker and thinner points (14 resp. 15), the material strengths of which are higher (S.sub.o) resp. lower (S.sub.2) than is the difference between the radius of bolt (8) and that of bores (5). This improvement provides increased life and reduced chain expansion because the connecting spike completely fills up the bores.
