Beschreibung
Zusammenfassung:	A device includes a first body having a curved wall with a top surface that slopes away from the first body and a second body having an interior configured to receive the curved wall of the first body, the interior including a curved ramp with a sloped bottom ramp surface. The second body is mounted on the first body with the bottom surface of the curved ramp resting on the top surface of the curved wall. A compressible seal extends from the first body bottom, and a shaft projects from the second body through a passage in the first body and into the interior of the compressible seal. Rotating the bodies relative to each other causes the shaft to pull the seal against the first body and radially expand the seal against an interior wall of an opening in which the device is placed to form a seal therewith.
