A tracheostoma valve for attachment to a tracheostoma valve plaster may include a tubular base portion with a proximal opening through which inhaled and exhaled air enters and exits, respectively. A distal lid portion may be arranged distally of the tubular base portion. The distal lid portion may have a distal opening through which inhaled and exhaled air enters and exits, respectively. The tracheostoma valve may have a valve flap member for closing the distal opening via interaction between a front side of the valve flap member and an edge of the distal opening. A valve retaining arm may be included for interaction with the valve flap member to prevent the valve flap member from interacting with the distal opening.
