Locking elements (4 and 5) are evenly distributed along the length of the frame members in a grooved area between the outer frame (1) and the casement (3) of a safety window. A locking element (4 or 5) rigidly secured to the outer frame (1) or to the casement (3) may be coupled to a respective locking element (4 or 5) movably secured to the casement (3) or the outer frame (1) when the casement (3) is in closed position. To ensure that the casement (3) may be sufficiently safely locked, without impairing the burglar-proof and attack-resistant effect, within the outer frame (1) by means of a turning and tilting fixture (8), the turning and tilting fixture (8) is attached outside the grooved area on the inside of the safety window and the locking elements (4 or 5) are inside the grooved area. <IMAGE> |
