Abstract

Cette invention concerne un tuba (50) pour appareil respiratoire de plongée, lequel tuba, lorsque l'on regarde sa section dans le sens longitudinal (50a), comprend une paroi circonférentielle (51) comportant des parties épaisses orientées vers l'extérieur (52) et planes à la surface circonférentielle interne de ladite paroi, ainsi que des parties minces repliées vers l'intérieur selon une faible courbure, lesdites parties étant disposées de manière alternée. Etant donné que la surface circonférentielle interne (51a) est pratiquement plane, il n'y a aucun risque de problème sanitaire comme on en voit dans des tubas à soufflet où des matières sales s'accumulent dans les parties renfoncement et entraînent la propagation de germes divers. Les parties fines assurent en outre la flexion nécessaire du tuba.
