    • A door hinged in a frame at one edge has a pivotal locking element along its other edge, with a longitudinal groove cooperatively receiving a counter-locking projection on the frame. The locking element includes a rotation stop to prevent the rotation of the door beyond closed position. The locking element is sufficiently rotatable about its pivotal mounting that its groove is disengaged from the locking projection for opening the door. A spring interconnects the locking element and the door for biasing the locking element in open or closed position. Grips are fastened respectively on one side of the door and to the locking element on the other side of the door. The rotation stop has an angularly arranged plate extending into an opening in the door with a projection on its free edge registerable with a corresponding projection on the door to limit opening pivotal movements of the locking element. A blocking element normaly biased to retain the locking element against pivotal movement is manually movable from one or both sides of the door to an unblocking position. The door hinge includes a flexible plastic strip anchored respectively to the door and door frame.
