A convoluted boot has a boot portion with annular folds, and collar portions adjoining the boot portion at both ends. A ventilation aperture is formed in the smaller one of the collar portions, the convoluted boot is provided for a universal joint which has an outer joint part and an inner joint part connected to a driveshaft. A larger collar portion is securable to the outer joint part and a smaller collar portion to the driveshaft. Inside the boot portion, near the smaller one of the collar portions, there is arranged an annular lip which is dimensioned in such a way that, with the driveshaft being axially aligned relative to the outer joint part, it rests under pre-tension against the driveshaft.
