A venting device, particularly for fluid storing reservoirs such as tanks, comprising a connecting part for establishing an air-conducting and/or fluid-conducting connection to the inside of the reservoir and comprising a closing part, which can be removed from the connecting part and which is provided, in particular, in the form of a closure cap. When the closure cap is fastened, at least one leakage point in the form of an air exchange opening exists between the closure cap and the connecting part. By virtue of the fact that a labyrinth-like seal effectively seals the respective leakage point at least from penetrants such as water and/or cleaning chemicals while not impairing an air exchange for the actual venting, the system of seal passages inside the labyrinth seal prevents the unwanted damage causing entry of the respective penetrant, also in the form of dirt or dust, into the reservoir or tank interior.
