The device also comprises a second tubular element at least partly overlapped with the internal duct and comprising lateral walls which extend around the internal duct and divide the chamber into two portions communicating with each other at the level of the bottom of the chamber; the internal portion is in communication with the internal volume of the internal duct, while the external portion is in communication with the second section of the first tubular element; the second tubular element is provided with a first opening interposed between the second section of the first tubular element and the second end of the internal duct. The device further comprises means for closing the first opening of the second tubular element.
