Abstract

Fully integrated self-contained connectors for standard tubes include a first annular member having an axial bore preferably of a continuously hollow-cylindrical configuration for receiving ferrules of those standard tubes. A locking arrangement peripheral of the first annular member carries locking members extending through openings in that first annular member for retaining a ferrule at a tube retention shoulder in a locking position. At least one further annular member is axially slidable on the first annular member and houses the locking arrangement outside that first annular member. The locking members are actuated to a locking position upon axial sliding of the further annular member in one direction. Conversely, the locking members are actuated to a release position upon axial sliding movement of the further annular member in another direction. The further annular member may define one or more internal ramps for that purpose. If two further annular members are employed, then they preferably are axially slidable on the first annular member in a push-pull manner relative to each other.
