End fitting for holding a high pressure capillary tube
First Claim
1. A fitting for holding a tube relative to a cooperating component, comprising an elongated externally threaded tubular body adapted to fit over the tube and be threaded to the cooperating component, said body having gripping means normally spaced from the tube but suited to be shifted to contact and tightly hold said tube, finger operated actuating member carried on the body, and cooperating cam means on said actuating member and body operable upon axial actuating member/body movement in one relative direction to shift said gripping means tightly against the tube and operable upon axial actuating member/body movement in the opposite direction to release the gripping means from the tube.

Abstract
The disclosed fitting has a tubular body externally threaded at one end, to allow the fitting to be positioned over a capillary tube and connected to a cooperating component. The fitting has opposed gripping jaws at its other end suited for being flexed against the capillary tube for holding it relative to the fitting. A tubular nut fits over the gripping jaws, and cam faces provided between the nut and jaws serve to tighten or release the jaws relative to the tube, depending on which direction the nut is shifted axially along the body. The outside tubular face of the actuating member is knurled, providing for reliable manual gripping and axial shifting the actuating member.
