ABSTRACT:
A window for insertion into an opening in a wall comprising a first frame which is adapted to abut against the outer face of the wall, a frame member provided with a rebate for a window pane and a second frame with a flange adapted to abut against the inner face of the wall. The frame member is integral with the first frame and adapted to cover the core of the wall, and includes a plurality of pairs of ribs. The ribs of each pair are connected by a strip to form an elongated opening therebetween. The second frame includes a toothed connection device consisting of tongues provided with a toothing and arranged in the longitudinal direction of the frame, the insertion of the window comprising clipping together the two frames from each side of the wall. In order to make it possible to manufacture the window frames as single pieces by injection molding, and at the same time to obtain a strong resistance to burglary, the tongues are divided into a number of spaced tongues on the second frame, the connection device on the first frame comprising correspondingly spaced openings, and the toothing is arranged on the narrow sides of the tongues to cooperate with a toothing arranged on ribs on the frame member running transverse to the frame member.
