What is claimed is: 1. A dielectric barrier discharge lamp comprising a discharge vessel and having at least two electrodes which are fitted to the outside of the discharge vessel, the electrodes being in the form of rods and being in the form of a plug connection element at one end. 2. The discharge lamp as claimed in claim 1, in which the electrodes are round rods. 3. The discharge lamp as claimed in claim 2, in which the electrodes are made from a deformable, electrically conductive plastic. 4. The discharge lamp as claimed in claim 2, having a discharge vessel which is elongate in the form of a tube and in which the electrodes are fitted to the outside of the discharge vessel along the longitudinal extent of the discharge vessel by means of an interlocking connection with a sleeve surrounding the electrodes, said sleeve partially surrounding the circumference of the discharge vessel perpendicular to the longitudinal extent but in the process leaving an aperture free for light radiation purposes. 5. The discharge lamp as claimed in claim 2 having a discharge vessel which is elongate in the form of a tube and having a conductive metallic shield which partially surrounds the discharge vessel and in the process leaves an angle of opening free for light radiation purposes, at least one shielding face of the shield being remote from the discharge vessel at its outermost end by a distance which is at least as great as half the average diameter of the discharge vessel transverse to the longitudinal extent. 6. The discharge lamp as claimed in claim 2 which has a plurality of discharge vessels, which are arranged next to one another in a row in the direction of longitudinal extent and can be operated jointly, the electrodes on the respective discharge vessels being connected to one another by their ends in the form of plug connection elements. 7. The discharge lamp as claimed in claim 2 having at least two opposing plug connection elements which are formed in complementary fashion to the electrode ends in the form of plug connection elements. 8. The discharge lamp as claimed in claim 1, in which the electrodes nestle up flat against the discharge vessel wall with a conductive, free-flowing substance. 9. The discharge lamp as claimed in claim 1 having a discharge vessel which is elongate in the form of a tube and in which the electrodes are filled to the outside of the discharge vessel along the longitudinal extent of the discharge vessel by means of an interlocking connection with a sleeve surrounding the electrodes, said sleeve partially surrounding the circumference of the discharge vessel perpendicular to the longitudinal extent but in the process leaving an aperture free for light radiation purposes. 10. The discharge lamp as claimed in claim 1 having a discharge vessel which is elongate in the form of a tube and having a conductive metallic shield which partially surrounds the discharge vessel and in the process leaves an angle of opening free for light radiation purposes, at least one shielding face of the shield being remote from the discharge vessel at its outermost end by a distance which is at least as great as half the average diameter of the discharge vessel transverse to the longitudinal extent. 11. The discharge lamp as claimed in claim 1 which has a plurality of discharge vessels, which are arranged next to one another in a row in the direction of longitudinal extent and can be operated jointly, the electrodes on the respective discharge vessels being connected to one another by their ends in the form of plug connection elements. 12. The discharge lamp as claimed in claim 1 having at least two opposing plug connection elements which are formed in complementary fashion to the electrode ends in the form of plug connection elements. 13. The discharge lamp as claimed in claim 12, in which the plug connection elements and opposing plug connection elements are designed such that the plug connection can be detached without any damage being caused. 14. The discharge lamp as claimed in claim 12, in which the plug connection elements and opposing plug connection elements are designed such that the plug connection can be produced by means of a purely translatory movement. 15. The discharge lamp as claimed in claim 13, in which the plug connection elements at least partially surround the opposing plug connection elements, or vice versa. 16. An illumination system having the dielectric barrier discharge lamp as claimed in claim 1, which has a discharge vessel which is elongate in the form of a tube and contacts, which are fitted at one end of the discharge vessel, for electrically connecting the lamp, and having an electronic ballast for the purpose of operating the lamp, a plug connection element being fixedly connected to a housing of the ballast, said plug connection element being designed such that the lamp can be connected to the ballast with the end having the contacts as the complementary plug connection element by being plugged together with the plug connection element of the housing. 17. A method for making contact with the discharge lamp as claimed in claim 1, in which in each case one end of the rod-shaped electrodes, as the plug connection element, is plugged together with a complementary opposing plug connection element, and the discharge lamp is thus electrically connected. 18. The method as claimed in claim 17, in which plugging-in takes place in purely translatory fashion. 19. The method as claimed in claim 17, in which the plug connection is detached again, once the discharge lamp has been electrically connected, by the plug connection elements and the opposing plug connection elements being pulled apart from one another, and the lamp is therefore isolated from its electrical connection. 20. The use of the discharge lamp as claimed in claim 1 as a UV radiator for the purpose of illuminating a catalyst. 21. The use as claimed in claim 20, in which the catalyst is used for air purification purposes in a vehicle. 22. The discharge lamp as claimed in claim 1, in which the electrodes, transverse to their longitudinal extent, have a length and width that differ from each other by no more than a factor of 5. 23. A dielectric barrier discharge lamp comprising a discharge vessel and having at least two electrodes which are fitted to the outside of the discharge vessel, the electrodes being in the form of rods and being in the form of a plug connection element at one end, in which the electrodes are made from a deformable, electrically conductive plastic. 24. A dielectric barrier discharge lamp comprising a discharge vessel and having at least two electrodes which are fitted to the outside of the discharge vessel, the electrodes being in the form of rods and being in the form of a plug connection element at one end, in which the electrodes are round rods, and in which the electrodes nestle up flat against the discharge vessel wall with a conductive, free-flowing substance.
