ANCHORING DEVICE

摘要

An anchoring device (10) comprises a resilient sleeve (16) for receiving an elongate member, such as a bolt (18), and first and second stoppers (20, 21) for location on the bolt at respective ends of the sleeve. The sleeve (16) and the stoppers (20, 21) comprise polymer-based materials. Movement of the stoppers (20, 21) towards one another causes the sleeve (16) to expand radially. The inner first stopper (20) may engage one of the bolt head (22) and nut (24) to resist relative rotation thereof.
