What is claimed is: 1. A sealing sleeve in the form of a rolling boot comprising: a first larger collar; a second smaller, substantially cylindrical collar; and a wall portion positioned between the first and second collars and forming at least one axially open annular fold, wherein a concave inner surface of the at least one axially open annular fold comprises circumferentially distributed radial ribs, wherein head lines of the radial ribs are positioned on a conical face which opens from the second collar to the first collar, and wherein the at least one axially open annular fold directly adjoins the first collar and is convex towards the outside of the rolling boot. 2. A sleeve according to claim 1, wherein a wall thickness in the region of the axially open annular fold is substantially constant. 3. A sleeve according to claim 1 comprising first and second axially open annular folds wherein the second axially open annular fold adjoins the first annular fold and is concave towards the outside of the rolling boot. 4. A sleeve according to claim 3, wherein the first annular fold directly adjoins the first collar and is convex towards the outside of the rolling boot. 5. A constant velocity joint comprising: an outer joint part; an inner joint part coupled to the outer joint part by a plurality of torque transmitting balls held in a ball cage; a shaft connected to the inner joint part; and a sealing sleeve according to claim 1 wherein the first collar sealingly engages the outer joint part and the second collar sealingly engages the shaft. 6. A joint according to claim 5 comprising a cover connected to the outer joint part, and wherein the first collar sealingly engages the cover. 7. A sleeve according to claim 1, wherein the sleeve is made by blow-molding or injection-molding.
