Abstract
A through-wall sleeve assembly includes an elongate sleeve having an axial passage, open ends and a radially constrictible frustoconical flange at one of the ends. The sleeve is inserted through a bore in a wall, with the flange at the leading end of the sleeve so that the flange is constricted by the wall or by an outer tube inserted in the bore. The flange returns to an expanded, relaxed condition when it projects beyond a remote surface of the wall and forms a seal with the remote surface when the sleeve is drawn back. An item such as a nozzle, hook or eye having external threads is inserted in the axial passage and fixed relative to the sleeve.
