Abstract
An interconnection is provided for the tilt wand of a window blind. The interconnection includes a connector having a worm gear on one end and a transverse aperture extending through the opposed end. The aperture is formed to define opposed major and minor dimensions. The minor dimension is defined by a pair of opposed arcuate ribs formed in the aperture. The interconnection further includes a hook having a mounting end which also includes opposed major and minor dimensions. The mounted end is further configured to be urged past the arcuate ribs with appropriate deflection of the connector. However, rearwardly facing portions of the major dimensions area on the hook are configured to securely lock the hook in the transverse aperture of the connector. The interconnection further includes a sleeve for retaining the hook in its locked condition and a tilt wand which is engageable on the hook.
