A mounting fixture for a window tiltable about a horizontal axis comprises a guide rail (10) to be mounted on a vertical main frame member with a first track for a slide or roller member secured at the top of the window frame, and a second track for a slide shoe connected with one end of a guiding rod (12), the other end of which is connected with the one vertical side member of the window frame, approximately in the middle thereof. A supporting bar (14) is pivotally connected (15) at one end with the upper end of the guide rail and at its other end with the guiding rod (12). In order to allow the adaptation of the fixture to conform to mounting in a window main frame of smaller size than a standard module for which the fixture is determined, the pivotal junction (15) is located between one end of the supporting bar and the guide rail at a distance (a) from the upper end of the guide rail, thereby allowing to effect the adaptation of the fixture by shortening the guide rail from the upper end. <IMAGE>
