Without further elaboration, the foregoing will so fully explain the invention that others may readily adapt the same for use under various conditions of service.

I claim:

1. In a Venetian blind assembly of the type including a lifting rail and lifting cords having the lower ends connected to said lifting rail; quickdetachable connections between the lower ends of said cords and said rail; each connection including a bight carried by said rail; a hook carried by the lower end of the cord; and a sleeve telescoped over said hook; said sleeve having a downwardly opening notch at its lower end adapted to receive said bight, whereby accidental upward movement of said bight in said hook will cause said sleeve to ride up with said bight and still prevent said bight from becoming disengaged.

2. In a Venetian blind assembly of the type including a lifting rail and lifting cords having lower end adapted to be connected to said lifting rail; quick detachable connections between the lower ends of said cord and said rail; each connection including hook means assembled to the lower end of the lifting cord; bight means assembled to the center of said lifting rail and adapted to engage said hook meansyand retain ing means in the nature of a vertically slidable sleeve assembled on aid hook means to overlie said bight means when assembled and prevent accidental disengagement.

3. In a Venetian blind assembly of the type including a lifting rail and lifting cords having lower ends adapted to be connected to said lifting rail; quick detachable connections between the lower ends of said cord and said rail; each connection including bight means and hook means carried by said rail and cord; and gravity-held shield means when in lower position preventing disengagement of said hook and bight means.

4. In a Venetian blind assembly of the type including a lifting rail and lifting cords having lower ends adapted to be connected to said lifting rail; quick detachable connections between the lower ends of said cord and said rail; each connection including hook means assembled to the lower end of the lifting cord; bight means assembled to the center of said lifting rail and adapted to engage said hook means; retaining means in the nature of a vertically slidable sleeve assembled on said hook means to overlie said bight means when assembled and prevent accidental disengagement; and stop means carried by said hook means for preventing disassembly of said sleeve means when said detachable connection is disconnected.
