In order to prevent, but at least in order to hinder, the forced opening of a window or of a door, comprising a case frame (10) and a sash/leaf frame (12) composed of metal profiles (14, 16; 20, 22), in particular composed of a composite profile, undercut grooves (50, 52; 32, 34) for the guidance of fitting elements (36) and for receiving seals (62) being integrally formed on the frames (10, 12), the opposite grooves (50, 52; 34) of the frames (10, 12) are filled with profile bars (54, 56; 38) or legs of functionally unnecessary grooves are removed, with the result that there are no elements for the attachment of a forcing tool in the gap between the frames. <IMAGE>
