A multifunctional fluid shut-off device including an upstream shut-off element, a flow-rate limiter, and a downstream functional element. The upstream shut-off element presents a body in which at least one valve is disposed, and a downstream end includes an exit port to which the downstream functional element is operatively connected. At least one of the upstream shut-off element and the downstream functional element includes a retention mechanism for the flow-rate limiter. A unit including the downstream functional element is directly connected to the upstream shut-off element containing in its interior the flow-rate limiter.

1. A multifunctional fluid shut-off device comprising: an upstream shut-off element includinga body in which at least one valve is disposed, anda downstream end having an exit port;a flow-rate limiter;a delivery nozzle that is operatively connected to the exit port of the upstream shut-off element; anda connection member including gripping elements and respective gripping counter-elements arranged tangentially to said upstream shut off element and said delivery nozzle and insertable through said exit port via which the delivery nozzle is connected to the exit port of the upstream shut-off element such that the delivery nozzle is continuously rotatable with respect to the upstream shut-off element without disconnecting therefrom;wherein at least one of the upstream shut-off element and the delivery nozzle includes retention means for the flow-rate limiter, andwherein the delivery nozzle is directly connected to the upstream shut-off element and contains in an interior thereof the flow-rate limiter. 2. A multifunctional shut-off device as claimed in claim 1, wherein the retention means includes direct retention means configured to retain the flow-rate limiter in a direct manner. 3. A multifunctional shut-off device as claimed in claim 2, wherein the direct retention means is located where the delivery nozzle is directly connected operatively to the upstream shut-off element. 4. A multifunctional shut-off device as claimed in claim 1, wherein the delivery nozzle includes a ball joint at a downstream end thereof. 5. A multifunctional shut-off device as claimed in claim 1, wherein the delivery nozzle is curved. 6. A multifunctional shut-off device as claimed in claim 1, wherein the flow-rate limiter is retained in position by the delivery nozzle operatively connected to the upstream shut-off element. 7. A multifunctional shut-off device as claimed in claim 2, wherein the direct retention means comprises a seat disposed in the exit port of the upstream shut-off element to at least partially house the flow-rate limiter. 8. A multifunctional shut-off device as claimed in claim 2, wherein the direct retention means comprises a seat disposed in the delivery nozzle to at least partially contain and retain the flow-rate limiter. 9. A multifunctional shut-off device as claimed in claim 1, wherein an upstream portion of the delivery nozzle is inserted into an exit housing in the exit port of the upstream shut-off element. 10. A multifunctional shut-off device as claimed in claim 9, wherein the exit housing comprises a seal element. 11. A multifunctional shut-off device as claimed in claim 1, wherein the gripping elements comprise at least one tangential hole in which a fixing pin is disposed. 12. A multifunctional shut-off device as claimed in claim 11, wherein the fixing pin is a fixing bolt. 13. A multifunctional shut-off device as claimed in claim 1, wherein the gripping counter-elements comprise a stop collar disposed on an upstream portion of the delivery nozzle. 14. A multifunctional shut-off device as claimed in claim 13, further comprising a stabilizer collar disposed on the upstream portion of the delivery nozzle. 15. A multifunctional shut-off device as claimed in claim 1, wherein the flow-rate limiter comprises at least one flexible throat and a divergent portion, a base of the divergent portion including a base housing operatively facing upstream to at least partially receive the flexible throat. 16. A multifunctional shut-off device as claimed in claim 15, wherein the base housing of the divergent portion includes a projecting edge that interferes with the delivery nozzle to prevent downstream sliding of the flow-rate limiter. 17. A multifunctional shut-off device as claimed in claim 1, wherein within the body a meter is connected in series with the valve. 18. A delivery nozzle configured to operatively connect to an exit port of an upstream shut-off element, comprising: direct retention means to retain a flow-rate limiter such that the flow-rate limiter lies at least partially within the delivery nozzle; andgripping counter-elements that engage corresponding gripping elements of the upstream shut-off element, each of said gripping elements and gripping counter-elements arranged tangentially to said upstream shut off element and said delivery nozzle and insertable through said exit port, such that the delivery nozzle is secured to an exit port of the upstream shut-off element, the delivery nozzle being continuously rotatable with respect to the upstream shut-off element without disconnecting therefrom. 19. A delivery nozzle as claimed in claim 18, wherein the direct retention means is inside the delivery nozzle. 20. A delivery nozzle as claimed in claim 19, wherein the direct retention means comprises a seat for the flow-rate limiter so as to prevent the flow-rate limiter from sliding downstream. 21. A delivery nozzle as claimed in claim 18, wherein the gripping counter-elements comprise a stop collar disposed on an upstream portion of the delivery nozzle. 22. A delivery nozzle as claimed in claim 18, wherein the delivery nozzle is curved. 23. A delivery nozzle as claimed in claim 18, further comprising a ball joint at downstream end thereof. 24. An upstream shut-off element comprising: a body on which at least one valve is disposed, the body including a downstream end having an exit port that is operatively connected to a delivery nozzle;gripping elements that connect the delivery nozzle to the exit port of the upstream shut-off element, said gripping elements arranged tangentially to said upstream shut off element and said delivery nozzle and insertable through said exit port, the delivery nozzle being continuously rotatable with respect to the upstream shut-off element without disconnecting therefrom; anddirect retention means to retain a flow-rate limiter such that the flow-rate limiter lies inside the delivery nozzle directly connected to the upstream shut-off element. 25.
