Abstract: A window cover such as a blind is disclosed which has draw cords (50, 250) which are pulled to open and close the blind. A coupling member (52, 100, 260) is provided and has two parts which separate when a load is applied to the cord to prevent a strangling hazard if a child becomes entangled in the cord. A spring (220) or elastic band (270) forming a load take up member is provided to prevent unwanted separation of the coupling member (52, 100, 260) if a short duration load is applied to the coupling member such as maybe occur if the blind is improperly opened or closed or is allowed to drop under its own weight.
