Abstract
A fitting (30) for use with soft tubing (40) is disclosed. The fitting includes a threaded female member (36) defining an aperture for insertion therethrough of the tubing. The fitting further includes a male member (32) defining a generally tubular portion (46) adapted for insertion into the end of the tubing. The male member includes a radially extending flange for preventing the insertion of tubular portion into the tubing beyond a predetermined distance. The male member is further threaded for threading onto the female member. A sliding mandrel (48) is positioned on the tubular portion for axial movement thereof. The female member includes a generally inwardly projecting collar portion (64) for engaging the outer surface of the tubing, the collar portion cooperating with the sliding mandrel to maintain the tubing in the fitting when a tensile pull is exerted on the tubing.
