A tracheostoma valve () comprises a main air passage structure provided with a main valve arrangement. The tracheostoma valve is switchable in response to a spurt of inhalation air from a breathing condition into a speaking condition, while the tracheostoma valve is switchable in response to a spurt of exhalation air from said speaking condition into said breathing condition. The main valve arrangement comprises an at least partly flexible bistable wall portion which has a circumferential bordering edge. At least part of the bordering edge forms a hinging means around which the bistable wall portion is hingeable between a first stable position in which an orifice of the main air passage structure is being blocked, and a second stable position in which said orifice is released.
