One side of a door-leaf-side hinge-plate (5) part is fixed to the door leaf (4). The other side of the hinge-plate is swivel mounted on a door-frame side hinge plate part (3). An outer surface (10) of the door-leaf side hinge-plate part facing the door leaf has protuberances (11,12) fitting into recesses (13,14) in the door leaf. At least one protuberance (11) has a smaller diameter than that of its recess and has a hooked free end. |
