The improvements consist in that around the elastic fingers 2 extending the bottom of the bell-shaped diffusion chamber 1 there is an additional body formed of a ring, from which there projects a plurality of tongues 6 which occupy the longitudinal spaces between fingers 2 and bear short, thin lateral fins 7 for abutment on said fingers 2, the latter and the tongues 6 being bound by the outer elastic sleeve 8. The free ends of said fingers 2 are markedly bent outwards to form a bell-mouthed shape facilitating insertion of the nozzle 9 of the dryer in question, which nozzle comes to a stop on the internal constriction 10. <IMAGE>
