A convoluted boot (11) seals an annular gap between two parts which are non-rotatably connected to one another and articulatable relative to each other. The invention is especially useful at a constant velocity universal joint. The boot has a plurality of fold units (20) which each consist of two annular flanks (21, 22) connected to one another by an outer annular fold (23). Two fold units (20) are connected to one another by an inner annular fold (24). The boot has a first collar (14) to be fixed to one of the parts, and a second collar (15) to be fixed to the second one of the parts. The collar adjoin the longitudinally outer fold units (20). Annular ribs (27) are formed on the annular flanks (21, 22) at a distance from the outer annular folds (23) and the inner annular folds (24). |
