Abstract
A connecting device having a fastening ring which has an elliptical cross-section and a slot. Projections 18 are on the inner surface of major axis portions of the fastening ring. An outer ring, which also has an elliptical cross-section, larger than the fastening ring and from which a lever projects, is fitted around the outer surface of the fastening ring. When the fastening ring is initially placed on a post, the minor axis portions and the projections on the major axis portions contact the outer surface of the post. When the outer ring is rotated 90.degree. clockwise by means of the lever, the minor axis portions of the outer ring bear against the outside of the major axis portions of the fastening ring, thereby pressing them inwardly. In this way, the fastening ring is tightened and the slot narrows as a consequence. As a result, the fastening ring is securely attached to the post.
