The runner (3) for the vehicle track is fixed by a bolt (6) which is inserted in a slightly truncated shaft (7) transverse to the runner external face (17). The shaft is extended by a passage (16) emerging in the runner fixing face (19) opposite the external face and in the shaft bottom (18). The fixing bolt passes through the passage and is supported on the shaft bottom. A cap (8) located in the shaft covers the fixing bolt. The shaft has a flange and the cap has a groove which comprise the means (9) of retaining the cap. The cap external wall perfectly fits the shaft internal wall (7) so that their connection is sealed. The runner has a metal support (4) with a covering (5) which is in contact with the ground.
