1. A kitchen sink sprayer, comprising: a body enclosed in an outer enclosure for being gripped by a user and provided with a coupling to a flexible water supply hose, which is adapted to be connected to a faucet for adjusting the flow-rate between a closed position and an open position;said body comprising inside it a rod that has, at one end, a tip adapted to open selectively the access of the water to at least one duct for forming a central jet and to at least one duct for forming a peripheral jet, and is provided with an actuating element;wherein said actuating element comprises a tab that is connected to said rod and protrudes from the outer enclosure of the sprayer, at the lateral surface thereof, by an extent that is sufficient for contact grip by the user when it is necessary to actuate said rod to move it from one of its selection positions to the other and vice versa;wherein said coupling is structurally independent from the body and from the outer enclosure of the kitchen sink sprayer;wherein a flange portion of said coupling is enclosed by said outer enclosure;wherein said body, together with said coupling, is held in position in said outer enclosure by a plug, the plug being set against the body, which in turn is set against the flange portion of the coupling;wherein said body is not directly constrained to said coupling against translation away from said coupling along a longitudinal axis of the sprayer, said body being simply supported by the plug, said plug being constrained to said outer enclosure against translation along the longitudinal axis of the sprayer, so that said plug restrains in a longitudinal position said body otherwise free to move away from the coupling within the outer enclosure. 2. The sprayer according to claim 1, wherein said body is sandwiched between the coupling and the plug, the coupling and the plug being independently connected by the outer enclosure. 3. The sprayer according to claim 2, wherein said plug is threadedly connected within said outer enclosure, so as to pack the body against the coupling. 4. The sprayer according to claim 1, wherein said coupling is removably attached to the rest of the kitchen sink sprayer. 5. The sprayer according to claim 1, wherein said coupling comprises at least a first feature meant to releasably fix the kitchen sink sprayer to a mouth of the faucet and at least a second feature meant to connect the kitchen sink sprayer to the flexible water supply hose. 6. The sprayer according to claim 5, wherein said coupling has a tubular structure, the first feature being provided on an external surface and the second feature being provided on an internal surface thereof. 7. The sprayer according to claim 6, wherein said second feature is a thread. 8. The sprayer according to claim 5, wherein said coupling is removably attached to the rest of the kitchen sink sprayer. 9. The sprayer according to claim 1, wherein said rod has a longitudinal axis, said rod being slidingly guided in said body in a sliding direction corresponding to said longitudinal axis of said rod, and said tab being movably guided exclusively in a single sliding direction that is parallel to the longitudinal axis. 10. The sprayer according to claim 1, wherein said tab is connected to said rod in an intermediate position of said rod, said sprayer further comprising a guide for guiding the rod in its motion, which is arranged on opposite sides with respect to the coupling position of the tab on said rod. 11. The sprayer according to claim 10, wherein said guide comprises an upper seat arranged in the body, slidingly housing an upper end of the rod. 12. The sprayer according to claim 10, wherein said guide comprises walls of a hole made in an internal partition of the body, wherein the rod is slidingly received. 13. The sprayer according to claim 10, wherein said guide comprises an upper seat arranged in the body, slidingly housing an upper end of the rod, as well as walls of a hole made in an internal partition of the body, wherein the rod is slidingly received. 14. The sprayer according to claim 1, wherein the tab of the rod protrudes from the outer enclosure of the sprayer in a direction perpendicular to said longitudinal axis of said rod at a slot provided on said enclosure. 15. The sprayer according to claim 14, wherein the tab of the rod is solidly attached to the rod by threading. 16. The sprayer according to claim 1, wherein the tab of the rod is solidly attached to the rod. 17. The sprayer according to claim 1, wherein said coupling and said body comprise first and second mating elements, eccentric with respect to the longitudinal axis of the sprayer, that prevent a relative rotation between the coupling and the body about the longitudinal axis. 18. The sprayer according to claim 17, wherein said first and second mating elements are a tooth and respective recess, respectively, or are a recess and a tooth, respectively. 19. The sprayer according to claim 17, wherein said coupling has a tubular structure, wherein an external surface of said tubular structure is provided with at least one non-cylindrical portion that prevents a rotation of the coupling with respect to the outer enclosure. 20. The sprayer according to claim 1, further comprising a ring placed between the coupling and the outer enclosure.
