Abstract
A plastic barb clamp provides leakproof connection of a flexible tube in a barb fitting. The barb clamp includes a collet and a sleeve. The barb clamp is configured to fit snugly within the tube. The collet is slid over the tube. Annular retainers on the interior surface of the collet fit tightly around the tube and under an expanded portion of the barb fitting. The sleeve is then slid over the collet. As the sleeve moves over the collet, tangs on the collet are pushed radially inwardly into the tube and barb fitting. The exterior surface of the collet has radial projections or expanded diameter portions for locking with the sleeve. The sleeve has an annular projection or a reduced diameter portion on the interior surface of the sleeve to correspond to the exterior surface of the collet to provide a secure lock between the collet and sleeve. To properly orientate the sleeve relative to the collet, the sleeve and collet can be molded as one piece, wherein the sleeve and collet are connected by thin, frangible pieces of plastic.
