An axial and radial locking release collar adapted to be axially received on and to be removably fixed at any selected location along the length of an elongated shaft and radially locked in at least one direction around the shaft. The release collar includes an axially movable sleeve. Moveable balls are cammed into frictional engagement with the shaft. A tension ring includes angled segments removed from the inner surface thereof such that said movable balls are held in the angled segments to prevent radially movement around the shaft. The release collar may also be easily slid onto a threaded shaft and locked into place.

[ What is now claimed is:] [1.] An axial and radial locking release fastener adapted to be axially received on and to be removably fixed at any selected location along the length of an elongated element, comprising:a collar body having an axially extending passage extending therethrough for receiving said element, said collar body includes opening therethrough;radially movable balls located within the openings of said collar body;a sleeve surrounding said collar body and defining a space therebetween;a tension ring integrally associated with and surrounded by said sleeve, said tension ring being located in the space between said sleeve and said collar body, said sleeve and said tension ring being axially slidable as a unit with respect to said collar body between a locked position and an unlocked position, said tension ring having an end portion with a tapered inner surface, said tapered inner surface having a relatively small dimensioned segment which urges said movable balls radially inwardly into said passage in the locked position, and having a relatively large dimensioned segment accommodating radial movement of said movable balls out of said passage in the unlocked position; said tension ring further comprising angled recesses coinciding with at least a portion of the tapered inner surface of said tension ring, such that when rotational force is applied to said fastener about the elongated body, said movable balls are cammed against the shaft thus preventing said release fastener from rotating about the elongated element; andrelease means to allow the fastener to be unlocked and moved along the length of the elongated element.
