A breathing protector to be fitted in a tracheostoma is disclosed. The breathing protector comprises a housing with a distal part and a proximal part, a first opening at a distal end of the distal part, and a second opening at the proximal end of the breathing protector. A valve flap is arranged at the first opening to closingly engage with a valve seat circumferentially of the first opening. The valve flap and the valve seat create a main valve being in an open position during inhalation and in a closed position during normal vegetative exhalation through the breathing protector. A spring member spring biasing the distal part in relation to the proximal part is comprised in the breathing protector to create a relief valve, being in a closed position during normal vegetative exhalation and transiting into an open position when the pressure in the trachea and thus the breathing protector exceeds a threshold value corresponding to a discomforting high pressure in the trachea.
