Roof rack fastening

The vehicle roof has rails along its long edges, with the roof rack fastened to them via support feet. Each rail (3) has a constriction (10,11), to reduce its profile, for engagement with a tensioning clamp (8) of a support foot (5). The constriction has vertical ribs to limit horizontal movement of the clamp. Each roof rail is fastened in a welding channel (2) of the roof (1), projecting upwards, and each rail completely fills the channel.
