1. A valve for a container for dispensing pressurized fluid, having a valve body which is mountable on a container lid,a closure member which is arranged in a passage provided in the valve body,a sealing arranged on the closure member and formed of at least one disc-shaped sealing lip and which, when the closure member is in a closing position relative to the valve body, abuts on a valve seat of the valve body provided on the passage thereof, andholding means by means of which the closure member is displaceably arranged in the valve body and held in a closing position therein when the closure member is in a normal position, wherein upstream with respect to an outflow direction of the fluid, at least one wear protection device is associated with the at least one sealing lip, which the at least one wear protection device is provided as at least one retaining lip. 2. The valve of claim 1, wherein the retaining lip is provided with anchoring elements which are formed between recesses in the retaining lip. 3. The valve of claim 2, wherein the retaining lip is disc-shaped. 4. The valve according to claim 1, wherein the retaining lip is arranged at a distance from the at least one sealing lip so as to form a gap. 5. The valve of claim 2, wherein the recesses are formed in the disc-shaped retaining lip so as to be evenly distributed about the circumference. 6. The valve of claim 2, wherein the recesses of the at least one retaining lip have a geometry differing from each other. 7. The valve of claim 2, wherein the recesses have a U-shaped or a rectangular configuration. 8. The valve of claim 1, wherein the retaining lip has an outer periphery which is equal to, or smaller than, the outer periphery of the at least one sealing lip. 9. The valve of claim 1, wherein a punch portion of the closure member, which is arranged adjacent to the retaining lip and opposite the sealing lip with respect to the retaining lip, has an outer periphery which is equal to, or smaller than, the outer periphery of the retaining lip. 10. The valve of claim 1, wherein the thickness of the disc-shaped retaining lip is equal to, or smaller than, the thickness of the sealing lip. 11. The valve of claim 1, wherein at least the gap between the sealing lip and the retaining lip or the width or the thickness of the sealing lip as compared to the retaining lip are provided such that the sealing lip is deformable in the valve seat by the valve seat when in a closing position and an outer, leading edge facing the retaining lip abuts on said retaining lip or abuts on the retaining lip with at least a low force. 12. The valve of claim 1, wherein at least the gap between the retaining lip and the punch portion or the width or the thickness of the retaining lip with respect to the punch portion are provided such that the retaining lip is deformable by the sealing lip so as to be inclined in the direction of the punch portion and abuts on an annular surface of the punch portion or is arranged at a small distance therefrom. 13. The valve of claim 1, wherein the retaining lip is arranged separate from the valve seat when the closure member is in a closing position. 14. The valve of the claim 1, wherein the at least one retaining lip is formed integrally with the valve body. 15. The valve of claim 1, wherein the at least one retaining lip is formed as a slip-on ring on the closure member.
