The whistle has a mouth piece (11) and a resonating body (12), which are formed from two plastic parts by injection molding process. A bottle opener (20) formed in a wall of the body has two segments, where one segment is designed as a bar made of metal. The bar is inserted into the wall such that an outer contour of the bar follows the quadrantal contour of the other segment such that a free edge protrudes from the latter segment. |
