ABSTRACT:
A device is positioned for passing a lengthy object through an opening in a wall to which a flat plate made of a stable material is attached. The plate has a hole that corresponds to and is aligned with the opening. A one-piece rubber sleeve that surrounds the lengthy object is provided for its moisture-proof insertion, and has a lengthwise separation which can be closed. A circumferential groove is provided on the inside of the rubber sleeve and is designed to lay against the lengthy object; this groove contains a ring-shaped insert made of a flexible material. In addition, the rubber sleeve has an outwardly open circumferential recess at one outer axial end, to seal the edge that limits the hole in the plate.
