The invention relates to blinds, components of blinds and assembly of blinds, and particularly to the tilt mechanism of a Venetian blind. The tilt mechanism includes a slider element to which the cords of the cord ladder are attached. The slider element has a base portion fixedly mounted in an aperture of the head rail, and a sliding portion. The ladder cords are routed through holes in the base portion, through a void between the sliding portion and the base portion and out of the ends of the slider element. The ends of the ladder cords are secured proximate respective ends of the sliding portion. The void is divided into separate chambers and the holes of the base portion communicate each with a respective chamber. A further hole and chamber may be provided to accommodate a lift cord. Tangling of the cords is eliminated, and the compact arrangement allows a slim and attractive head rail to be used.
