Fireproof doors must not deform in the event of a fire such that gaps for the passage of flames are formed between case (1) and leaf (2, 3). In order to be able to satisfy this requirement with a low degree of structural outlay, the hinge-side rebates of case (1) and leaf (2, 3), in the closed position of the latter, engage one in the other by means of a convex profile (5), formed in a continuous manner on one rebate, and of a concave profile formed in a continuous manner on the other rebate.
