Abstract
A clamp (10) comprises a plastic molded threaded screw portion (12) and a molded U-shaped plastic clamp portion (26). The U-shaped plastic clamp portion (26) has two legs (28, 30) projecting from a base (32). One of the two legs (28) has molded plastic threads (29) which engage plastic threads (15) of the plastic threaded screw portion (12). The plastic molded screw portion (12) has a swivel portion (20) which swivels relative to the plastic molded screw portion. A method of making an injection molded plastic clamp (10) comprises molding a first plastic clamp portion (12) in a mold, molding a second U-shaped plastic clamp portion (26) to the first clamp portion in a mold containing the first clamp portion to form an assembled injection molded plastic clamp.
