Abstract
A barb clamp provides a leakproof connection of a flexible tube in a barbed fitting. The barb clamp includes a collet and sleeve. The barb fitting is configured to fit snugly within the tube. The collet is slid over the tube. Shelves 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 sleeve is moved over the collet until an annular projection on the interior surface of the sleeve sits within an annular groove of the collet. Radial ledges on the exterior surface of the collet provide a stop and lock to prevent the annular projection on the sleeve to move out of the annular groove of the collet.
