The invention relates to a hinge housing (10) which is flushly mounted in a recess (18) inside the wall (16a) of a door leaf (16) which is made of a thin-walled metal and provided with a metal pot-shaped part (12) whose top edge is projected and forms in single-piece a fixing flange (22) and a guard plate (14) disposed between the fixing flange (22) and the internal part of the door leaf. Said guard plate (14) comprises elastic snap-in pins (26) which are disposed in the a recess (24) thereof corresponding to the recess (18) of the door leaf (16) and which, in the fixed position thereof, encompass the edge area of the recess (18) of the door leaf (16) on the internal part of the wall. Said guard plate (14) comprises at least two through holes which are (30) remote from each other in the direction of an opening (20) associated with each of them and embodied in the wall (16a) of the door leaf (16) and two through openings (32) which are embodied in the fixing flange (22) and are crossedby the butt-joints (34b) of fastening screws (34) whose ends are screwed into a clamping plate (36). Elastically deformable fixing bodies (40) crossed by the butt-joints (34b) of the fastening screws(34) are arranged between the flat faces of the guard plate (14) oriented towards the wall (16a) of the door leaf (16) and the limiting faces of the clamping plates (36) opposite thereto and in the undistorted form thereof produce an external limitation of the openings (20) in the wall (16a) of the door leaf and of the clamping plate 36.
