ABSTRACT:
A blade holder for a louvre window comprises an elongated member having a longitudinally groove for retaining an end edge of a louvre blade, a rebate of cruciform cross-section formed in that surface of the elongated member which is disposed adjacent the surface of a window frame on which the blade holder is pivotally mounted, and a drive plate for pivotally mounting the elongated member on the window frame, the drive plate comprising a main body and a boss separated by a bearing portion, the bearing portion being in rotational engagement within an aperture in the window frame, and the boss having a cruciform cross-section so that it has a driving engagement with the rebate in the elongated member. Two hardened steel pins are mounted on the driving plate to extend axially through the boss to prevent removal of the louvre by sawing through the boss.
