A connector for a multiple element blind assembly includes a first coupling element for association with a first blind element, said first coupling element having a body and a projection extending therefrom. The projection includes a keying portion. Also provided is a second coupling element for association with a second blind element. The second coupling element has a body defining a bore therein, which includes a keyway portion. The keying portion is insertable into and keys with said keyway to a torque transferring portion such that torque applied to one of said coupling elements is transferred to the other coupling element. Also, the keying portion is only insertable into said keyway to said torque transferring portion when said first and second coupling elements are aligned within a single relative rotational range.
