A bar intended for fixing to the topside of a window or door comprises: a first cavity for accommodating a raising mechanism for raising cords for a covering for the window, which internal cavity is accessible from outside via holes in the bar for passage of a control cord and at least two cords which are connected for driving to the underside of the covering; a second cavity which extends in the longitudinal direction and which debouches via a constriction onto the outside of the bar, and serves to receive the upper edge of the covering which fits into the second cavity but is too wide to pass through the constriction; two profiles which together bound the first cavity, in at least one of which profiles said holes are present. |
