The device is based on an optionally single piece body (1), obtained by plastic moulding, of cylindrical configuration, with the opening and the corresponding axial and central neck (3) for the passing of a wick that, at its lower end, is immersed in an active substance contained in a vessel to which the device is applicable, having optional ribs (4) for holding and positioning the wick heating resistances, as well as projections (6) with cross channels (7) for the positioning of the ends of the electrical resistances wires, being supplemented with a piece (8) acting as a clip, that by means of a flap or arm (9) formed in it, the ends of the resistances are kept in the flutings (7), and allows the positioning of the contactors through which the electrical supply to those heating resistances is set up, a positioning that is carried out on an upper slot (10) set up in that piece (8) which has contactor connection flaps (11), and optionally a cover that assures a more reliable fastening by pressing on the upper edge of the clips (8).
