And then, the air flow escapes out of the main body 3 through air evacuation openings 46 provided in the latter.

According to a variant embodiment not shown in the figures, at least one, and for example each of the first and second contacts 26, 27 comprise several conductive tracks, for example two conductive tracks, which can be obtained by screen printing or by printing. According to such an embodiment of the invention, at least one, and preferably each, of the control device 23 and of the activation device 24 comprises an additional contact comprising at least one conductive element, such as a pad made of conductive material or a further conductive track that is configured to cooperate with the conductive tracks provided in the respective contact.

Naturally, the present invention is in no way limited to the described and illustrated embodiment which has been given solely by way of example. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
