Each circuit (fluid conduit or cable duct) is associated with a separate collector, of general annular shape, comprising two rings adapted and connected to each other so as to define at least one annular chamber therebetween, the first ring being fixed and integrally mounted on the fixed central spindle of the dwelling and the second ring being integrally connected to the rotating or revolving inhabitable assembly and said second ring being mounted so as to be capable of moving relative to the first ring. Said first ring is provided with at least one transverse passage by which each annular chamber communicate with a respective fixed conduit or duct.
