The device comprises: a strip wrapper (14) wound around an axis (16) such that the inner surface of a first end edge (18) is secured to the outer surface of a portion (20) of the wrapper (14) which is adjacent to a second end edge (22), which second edge (22) separates a first volume (24), which is designed to accommodate the heating body (10) and the nozzle (12), from a second volume (26) which is closed by the second edge (22) and by a portion (28) of the wrapper which is adjacent to the first edge (18) ; and clamping means which are located in the second volume (26), in order to exert a radial force on the second end edge (22) . The portion (28) of wrapper (14) has a projection (32) which protrudes radially into the distal portion of the second volume (26), and extends circumf erentially . The clamping means comprise a screw (36), and a first and a second element (38, 40) which are disposed in the said second volume (26) on opposite sides in relation to the projection (32) . The screw (36) has a head (42) and a threaded rod (46) . The first element (38) has a non-threaded through aperture (48), and the second element (40) has a threaded through aperture (50) . The apertures (48, 50) are aligned and oriented parallel to the axis (16) . The distal portion of the rod (46) is engaged in the second aperture (50), and the proximal portion of the threaded rod (46) passes freely through the first aperture (48) . |
