In this flexible intercommunication device made up of a succession of rings which are alternately rigid (7) and flexible (8), of overall rectangular shape having substantially horizontal sides (7H, 8H) and substantially vertical sides (7V, 8V), the flexible rings (8) are fixed, at their two horizontal sides (8H), solely to one of the two adjacent rigid rings (7), the said horizontal sides being mounted with the possibility of sliding horizontally with respect to the horizontal sides (7H) of the other of the two adjacent rigid rings (7). <IMAGE>
