Said device comprises a fixed part that can be connected to the steam supply conduit (1) of said machines and an easily interchangeable disposable part (26) containing all parts that come into contact with the milk. The invention is characterised in that components of the disposable parts and in some embodiments of the invention even the entire disposable part consist(s) of thin-walled plastic tubes of the drinking straw type, which can be produced in a cost-effective and environmentally friendly manner by extrusion and subsequent thermoplastic forming. The use of the inventive device obviates the need for the inconvenient cleaning of conventional foaming nozzles and eliminates hygiene problems.
