A whistle has a mouthpiece which is cushioned to minimize damage to the whistle and improve the comfort and safety of a user. The cushioning material is preferably injection moulded into a sleeve which locates between ridges integrally moulded with the whistle body. The body also has a plurality of projections for mating with the cushioning material. A web in an air inlet passage strengthens the mouthpiece to prevent collapse or fracture of the mouthpiece.
