ABSTRACT:
A releasable clip for purposes of locking a tube into a fitting is shown. The clip is formed as a ring with two or more arms that project from the ring portion. The arms project in a direction that is generally parallel to the tube axis, and are made from plastic or metal material and dimensioned so as to function as springing arms. At the end of the arms is an engaging portion that engages an interior abutting wall of the fitting. The ring portion inside diameter is disposed around the tube and engages an abutting projection (an external bead for example) on the tubing. The clip arms may also include portions at the end of the arms to facilitate installation. One or more pair of arms without the engaging portion may be used to facilitate installation by assisting in maintaining concentricity of the clip to the tube axis. A means for positioning the clip along the tube length is also shown.
