Abstract
A barb clamp is provided for fluid liquid or gaseous connection to a flexible tube, the flexible tube having an inner bore defined by a predetermined inner diameter for providing a fluid flow path. The barb clamp includes a barb connector having the same predetermined inner diameter as the flexible tube and a tapered end insertable into the tube. A sleeve and collet lock over the tubing and barb connector to prevent liquid material entering between the barb and tube. The tapered end of the barb connector terminates at a point so that there is no transition between the inner diameter of the tube and the inner diameter of the barb connector to provide no pressure differential in the tube between the outside and inside of the barb clamp.

A barbed fitting for insertion into a flexible tube having a predetermined inner diamter, the barbed fitting comprising:
- a nonmetal elongated body portion having a tubular configuration and a smooth inner bore with a constant diameter therethrough;
- and
- a nonmetal end portion for disposing within an end of the flexible tube, the end portion integrally connected to the elongated body portion, wherein the smooth inner bore continuously extends through the end portion, the end portion tapering to a sharp termination point.
A barb clamp for a flexible tube having a predetermined inner diameter defining a fluid passageway therein and an outer surface, the clamp comprising:
- a barb connector having a tubular configuration with a first end for disposing within an end of the flexible tube and a sharp edge terminating the first end, the barb connector having a smooth inner bore;
- a collet slidable over the first end of the barb connector and the outer surface of the flexible tube;
