Apparatus for releasably and adjustably mounting a tubular device to an object, the apparatus comprising: a base comprising a central opening passing therethrough, the base being magnetized so as to provide a magnetic field at the central opening of the base; a generally spherical ball sized to be received in the central opening of the base but sized so as to not pass through the central opening, the generally spherical ball comprising a central bore passing therethrough; wherein the ball comprises a ferrous material which is attracted to the magnetic field at the central opening of the base, and further wherein the magnetic field at the central opening of the base is sufficiently strong so as to retain the ball in the central opening of the base; and wherein the central bore of the generally spherical ball is configured to slidably receive a tubular device therein, and further wherein the base is configured to be mounted to an object.
