Abstract: A protective cover for the ends of reinforcing bars has a cylindrical tube having upper and lower ends. A cap is mounted on the upper end of the tube and is comprised of a continuous circular wall extending upwardly and outwardly from the upper end of the tube, with a bottom covering the top of the tube. A post extends upwardly from the center of the bottom, and a plurality of spaced rib elements are secured to and extend radially outwardly from the post for connection to the wall. A canopy is secured to the upper edge of the wall and extends slightly downwardly therefrom. The canopy has a circular perimeter which has a downwardly extending circular flange extending therearound. The ribs are tied together by secondary ribs. Friction bars are located within the tube to create friction between the tub and a bar upon which it is mounted.

Abstract: An improved structure is provided for connecting an end of an elongate member to an end plate. The end plate is provided with an aperture for receiving a fastener having a threaded shank adapted for extending through the aperture and having a head for engaging the end plate. The structure includes at least a first slot in the elongate member. A retaining member is provided for being positioned in the elongate member slot. The retaining member has two oppositely extending end portions for each projecting laterally beyond the elongate member and engaging the elongate member. The retaining member defines a threaded bore for threadingly receiving the threaded shank of the fastener.
