Clip nuts

In a clip nut comprising a clip-body having a top wall with first and second ends, a bottom wall with first and second ends, an end wall connecting the second end of the top wall to the second end of the bottom wall, and forming a closed end for said clip-body, with the opposite end of the clip-body being open, a pair of sidewalls projecting upwardly from the top wall and including a first pair of aligned openings, and a second pair of aligned openings in the first ends of the top and bottom walls;

• and
• a nut having a base, a tubular body extending upwardly from the base and including an internally threaded central opening, said base including a pair of tabs projecting radially outwardly from it on diametrically opposite locations on said base;
• wherein the base of the nut sets on the top wall between the sidewalls and the tabs on the nut extend through the first pair of aligned openings and position the opening in said tubular body in substantial coaxially alignment with the second pair of aligned openings, wherein in use a member is received between the top and bottom walls and a bolt is inserted first through the opening in the bottom wall, then through the member, and is then screwed into the threaded central opening and the improvement comprising:
• said clip-body being constructed from plastic and including a transverse hinge section in the top wall closely adjacent where the top wall meets the end wall, and wherein the sidewalls extend upwardly from the top wall substantially throughout the full extent of the top wall between the hinge section and the open end of the clip-body, and wherein the sidewalls stiffen the top wall and substantially restrict bending of the top wall to the hinge section region of the top wall when the screw is tightened.
