Abstract
The present disclosure relates to a device for preventing access to a conduit. The device comprises top and bottom compression plates and a compressible member between the compression plates. A bolt has a first end mounted to the bottom compression plate and a shaft passing through openings of the compressible member and of the top compression plate. The bolt has a head proximate its second end. The head of the bolt extends beyond a major diameter of the threaded shaft. At least a portion of the shaft is a threaded shaft. The head of the bolt prevents a nut mounted on the threaded shaft between the head and the top compression plate from being dismounted from the device. A fluid passage may extend in the compressible member between the top and bottom compression plates to allow a fluid to bypass the device.

A device for preventing access to a conduit, comprising:
- a top compression plate;
- a bottom compression plate;
- a compressible member between the top and bottom compression plates;
- a bolt having a first end mounted to the bottom compression plate and a shaft passing through a central opening of the compressible member and through openings of the top compression plate, the bolt having a second end opposite from the first end and a head proximate to the second end, at least a portion of the shaft proximate to the second end being a threaded shaft, the head of the bolt extending beyond a major diameter of the threaded shaft;
- and
- a nut mounted on the threaded shaft between the head and the top compression plate;
- wherein the compressible member comprises a fluid passage formed on an outer periphery of the compressible member and extending between the top and bottom compression plates, the top and bottom compression plates being sized and configured to allow passage of a fluid via the fluid passage between the top and bottom compression plates.
