This nozzle comprises a body 2 of an elongated shape inside which is formed an axial bore comprising a rear part 3 and a front part 4 forming a channel of reduced cross-section. The part 3 serves to house a cylindrical part 6 delimiting, with the body, an annular chamber 7 supplied with a first fluid. The part 3 comprises axial passages 14 supplied from the rear end with a second fluid. The two fluids mix upstream or in the front part 4 of the bore to form snow at the exit from the nozzle. <IMAGE>
