In a breakaway device for a Roman shade a male member has an aperture through which the lift cord passes and a female member through which the lift cord passes, such that the male member and the female member are independently moveable relative to the lift cord. The female member has a cavity sized and configured to receive the male member. Tabs extend from the male member and fit into slots in the female member when the male member is in the cavity. A downward and outward force on the lift cord causes the male member and the female member to separate from one another. An upward force or a downward force on the lift cords will not cause separation.
