In a therapeutic device for respiratory passages (1) for the treatment of respiratory problems, comprising at least one pipe section (3) which has at least one passage duct (4) through which air (5) can be inhaled or exhaled and at least one elastic hose (8) with its first free end (9) arranged on one free end on one of the pipe sections (3) and which can vibrate during inhalation or exhalation in one flow direction (6) because of the throughflow, the hose (8) should be able to be exchanged in a straightforward and uncomplicated procedure even by people with restricted finger mobility or manual dexterity. This task is achieved in that the circumference of the first free end (9) of the hose (8) is smaller than or equal to the circumference of the passage duct (4) of the free end of the pipe section (3), that the width (b) of one of the long sides (14) of the first free end (9) of the hose (8) is larger than the width or diameter (d) of the passage duct (4), that areas of the hose (8) c an be inserted into the passage duct (4) by compressing the long side (14) and that the hose (8) is held in the passage duct (4) by a preload force after having been inserted.En un dispositivo terapéutico para vías respiratorias (1) para el tratamiento contra problemas respiratorios, que comprende al menos una sección de tubo (3) que tiene al menos un conducto de paso (4) a través del cual se puede inhalar o exhalar aire (5) y al menos un tubo flexible elástico (8) con su primer extremo libre (9) dispuesto en un extremo libre en una de las secciones del tubo (3) y que puede vibrar durante la inhalación o exhalación en una dirección de flujo (6) debido a la circulación del caudal el tubo flexible (8) se debe poder cambiar mediante un procedimiento sencillo y sin complicaciones incluso por personas con movilidad limitada en los dedos o poca destreza manual. Esta tarea se logra ya que la circunferencia del primer extremo libre (9) del tubo flexible (8) es menor o igual a la circunferencia
