Abstract
A snap-on valve sleeve for a check valve designed to be rigidly and sealingly secured within the end of an elastomeric tube. The sleeve includes a plurality of inwardly disposed barb segments positioned in mating alignment with an annular protrusion positioned about the outer surface of the valve body. The annular protrusion comprises an upward rearwardly sloped surface and a flat step surface perpendicular to the outer surface of the valve body. The check valve is inserted into the end of the tube. The outer edge of the end of the tube slides over the step surface positioning the tube along a partial length of the valve body. The sleeve is positioned over the forward end of the valve body and forced along the length of the valve body until the barb segments ride up the upward rearwardly sloped surface and then snap over the sloped surface to compress and seal the tube between the valve body and sleeve. The sleeve cannot be disengaged from the body thereby precluding breakage of the seal between the tube and body.
