A nonreturn valve (10) for a compact ventilation system (100), includes a recoil membrane (20) and a holding element (40) for holding the recoil membrane (20) and for fastening the nonreturn valve (10) at a flow duct (110) of the compact ventilation system (100). The recoil membrane (20) has at least one mechanical stabilizing section (22) for cooperating with at least one mechanical counter-stabilizing section (42) of the holding element (40) or of the flow duct (110) of the compact ventilation system (100). At least one opening section (24) is provided for the defined movement of the recoil membrane (20) during the opening of the nonreturn valve (10) and a holding section (26) is provided for holding the recoil membrane (20) at a counter-holding section (46) of the holding element (40). A compact ventilation system (100) is provided with such a nonreturn valve (10).
