1. A device for locking wheel rims for vehicles on repair workshop machines, particularly tire-changing machines or the like, comprising: at least one supporting structure rotatably positioned around a work axis with a repair workshop machine and having at least a resting portion for a wheel rim for vehicles;at least one locking element removably associated with at least one fastening element on said supporting structure, the fastening element surrounding the locking element; andat least one movement arrangement disposed within the supporting structure and comprising: a) a main actuator cylinder with fluid operation being configured for moving said fastening element from a release position wherein said locking element is disengaged from said rim, to a retention position wherein said locking element is engaged on said rim,b) at least one auxiliary actuator cylinder with fluid operation being configured for moving said fastening element from said release position to said retention position of the rim, the main actuator cylinder and at least one auxiliary actuator cylinder surrounding the fastening element, andc) a feeding mouth for a fluid, said feeding mouth being connected to at least one of said main actuator cylinder and said at least one auxiliary actuator cylinder. 2. The device according to claim 1, wherein said movement arrangement comprises a transit channel for the fluid introduced through said feeding mouth from said main actuator cylinder to said auxiliary actuator cylinder, or vice versa. 3. The device according to claim 2, wherein said main actuator cylinder comprises a main piston for pushing said fastening element. 4. The device according to claim 3, wherein said main actuator cylinder comprises a main inner chamber connected to said feeding mouth for the fluid. 5. The device according to claim 4, wherein said at least one auxiliary actuator cylinder comprises an auxiliary piston for pushing said main piston. 6. The device according to claim 5, wherein said at least one auxiliary actuator cylinder comprises an auxiliary inner chamber connected to said main inner chamber through said transit channel. 7. The device according to claim 1, wherein said movement arrangement comprises a plurality of said auxiliary actuator cylinders. 8. The device according to claim 1, wherein said resting portion comprises at least one opening for the insertion of an extremal section of said locking element, said rim being positionable on said resting portion with a central hole corresponding to said opening. 9. The device according to claim 8, wherein said fastening element comprises a housing body of said extremal section of the locking element, when it is inserted through said opening, and coupling means between said extremal section and said housing body. 10. The device according to claim 9, wherein said coupling means comprise bayonet latches. 11. The device according to claim 9, wherein said coupling means comprise at least one first shoulder made on an outer surface of said extremal section, said first shoulder being adapted to be coupled in a removable way to a respective second shoulder made on an inner surface of said housing body. 12. The device according to claim 11, wherein said locking element comprises a plurality of said first shoulders, made at a distance from one another along said extremal section. 13. The device according to claim 9, wherein said housing body slides on said supporting structure via said movement arrangement, for positioning said locking element between said release position and said retention position. 14. The device according to claim 13, wherein said housing body slides inside a channel delimited by an inner wall of said supporting structure. 15. The device according to claim 14, wherein a liner of said main and auxiliary actuator cylinders is delimited by at least one of an outer wall and said inner wall of said supporting structure. 16. The device according to claim 15, wherein said outer wall, said inner wall and said housing body are substantially cylinder-shaped and coaxial to one another. 17. The device according to claim 6, wherein at least a portion of said auxiliary piston slides inside said main inner chamber or another adjacent auxiliary inner chamber and has at least a thrust surface of said main piston or another auxiliary piston. 18. The device according to claim 1, wherein said movement arrangement comprises a supplementary actuator cylinder with fluid operation connected to a supplementary mouth for feeding a fluid and suitable for moving said fastening element from said retention position to said release position. 19. The device according to claim 18, wherein said supplementary actuator cylinder comprises a supplementary piston for pushing said fastening element. 20. The device according to claim 19, wherein said supplementary actuator cylinder comprises a supplementary inner chamber connected to said supplementary mouth for feeding the fluid. 21. The device according to claim 1, wherein the locking element comprises a pressing element with a substantially widened conformation, said locking element being adapted for contacting said rim in said retention position. 22. The device according to claim 1, wherein said locking element has a substantially elongated shape. 23. The device according to claim 1, wherein said pressing element has a substantially truncated-cone shape, with a vertex turned towards said extremal section and is substantially coaxial with respect to a longitudinal axis of said locking element. 24. The device according to claim 1, wherein said locking element has an extremity opposite said extremal section, said extremity being equipped with a grip handle.
