A security door (10) comprises a frame structure (12), in the lateral surface of which a plurality of doorways (14, 16, 18, 20) is constructed, wherein a first doorway (14) constructed in the lateral surface of the frame structure (12) has a first width along an inner circumference of the frame structure (12), and wherein lateral surface portions (22, 24) delimiting the first doorway (14) in a first direction (R 1 ) and a second direction (R 2 ), opposing the first direction (R 1 ), along the inner circumference of the frame structure (12) have a second width. The security door (10) further comprises a lock element (30) received in the frame structure (12). The lock element (30) comprises a first segment (32), which is movable along the inner circumference of the frame structure (12) relative to the frame structure (12), and a second segment (34), which is movable independently of the first segment (32) along the inner circumference of the frame structure (12) relative to the frame structure (12), wherein the first segment (32) of the lock element (30) is dimensioned so that, in a position in which it closes the first doorway (14), it also closes a second doorway (16) adjacent to the first doorway (14) in the first direction (R 1 ) along the inner circumference of the frame structure (12). |
