Claim:
1. A device, comprising: a mounting plate, having a base portion and a stem portion, wherein the base portion has an outer edge with a first diameter; and a sleeve element slidably engaged with the stem portion of the mounting plate, with the sleeve element comprising an external surface and an internal surface, with the external surface having a second diameter that is smaller than the first diameter of the outer edge of the mounting plate base portion, with the internal surface defining a cavity extending axially therethrough, the sleeve element further having a first axial end and a second axial end, with the internal surface at the first axial end forming a retaining ring receiving compartment, wherein the sleeve element further has a body portion with a first axial end and a second axial end, and wherein the retaining ring receiving compartment includes a first retaining wall integrally formed with and extending radially outwardly from the sleeve element body portion, an outer wall element integrally formed with and extending axially toward the first axial end from the first retaining wall, and a second retaining wall integrally formed with and extending radially inwardly from the outer wall element, wherein the sleeve element, the retaining ring receiving compartment first retaining wall, the retaining ring outer wall element and the retaining ring second retaining wall are monolithic, and wherein the sleeve element body portion internal surface tapers in substantially frustoconical form from a first radial distance proximate the sleeve element body portion first axial end to a second radial distance proximate the sleeve element body portion second axial end, wherein the first radial distance is larger than the second radial distance.
