Closure lock (1) of parts (2, 3) which are stressed in vibration and are connected to a rotating closure (4), of which parts one is fixed and the other is held such that it can rotate for opening, especially for an air-filter housing for goods vehicle internal-combustion engines, the closure lock (1) having a bolt (5) which can be opened against a restoring force and returns automatically to its closed position. In detail, the closure lock (1) has a retaining strip (7), running in the rotation direction, on the rotation part (3), and a closing strip (6), and the bolt (5) which can be displaced in a groove (8) in the fixed part (2) at right angles to the rotation direction, it being possible to fix the bolt (5) on the closing strip (6) in the closed position, said bolt (5) resting on the retaining strip (7) in the open position and, after being released by rotating the rotating part (3), occupying a position, which makes renewed fixing possible by rotation, because of the restoring force of the spring projections on the bolt (5). <IMAGE>
