Abstract

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).
