ABSTRACT:
A resilient clip in three integrally joined sections: a central or web section centered on a z-axis, and two extensions from the web extending along x- and y-axes. Each section or portion may be described as a split sleeve and has a generally cylindrical opening therethrough, respectively centered on the same three axes. These openings are contoured and disposed to snugly receive a reinforcing bar or rod and a pair of corner legs of a generally rectangular stirrup, a piece of heavy wire bent into a rectangular shape and receiving reinforcing bars at its four corners, holding them in such positions to maintain the planned spacing between rebars. Each of the central openings through the three parts is joined to the outside by a lateral slit defined by a pair of lips that are forced apart by pushing the clip onto the steel member. The extensions of the clip may each have a second cylindrical opening which is parallel to the first mentioned and closely adjacent thereto, to accommodate parallel legs of the stirrup when the two ends thereof overlap. The pair of extensions may either face in opposite directions, or they may face in the same direction, whereby both extensions may be simultaneously mounted on the legs of a stirrup corner by a single pushing action. The clip may also be used to secure together any three mutually perpendicular rods or bars.
