In this door frame, frame elements are connected together mechanically positively and non-detachably in pluggable manner. Tongues (28, 30, 32, 34) of a lintel element (3) are plugged into slots (37, 38, 39, 40) of a door post (2) and additional element (45) is pushed at the door post end onto the tongues (28, 30, 32, 34 ), which project out of the slots of the door post (2), of the lintel element (3). Thereafter, the additional element (45) is moved downwardly, wherein tongues (47, 49, 50, 51) of the additional element (45) detent in slots (29, 31, 33, 35) of the lintel element (3). The upward movement of the additional element (45) is prevented by means of a tongue (44) in that this is bent into a recess (42) of the door post (2).
