Abstract
Abstract A housing, mountable on a panel, provided with a stepped bore therethrough into which a slidable bar is positioned to extend beyond each side of the housing. One end of the bar is provided with a finger-grip handle so that the bar may be pushed and pulled through the housing into and out of a predrilled bore in a second, relatively movable panel. When the bar is pulled toward the user and out of the predrilled bore, a larger diameter section thereof abuts a step in the housing bore to prevent the bar from being completely removed. When the bar is completely pushed in, a sphere may fall into a fillet on the bar. Pulling on the bar lightly will cause the fillet to push the sphere out of the way so that the bar can be withdrawn. A flange or cam, which may be rotated by means of a key lock, may be so located within the housing that it can positively retain the sphere against the fillet in order to positively prevent withdrawal of the bar.
