ABSTRACT:
An energy-absorbing shock cell for mounting bumper or barrier devices on legs or other members of offshore oil rig structures having inner and outer metal tubes connected by an intervening rubber sleevelike body is provided with snubbing means engageable between limit members rigidly mounted in spaced relation on the inner and outer tubes to prevent telescopic outward movement of said inner tube from the outer tube beyond a certain predetermined location, thereby preventing the inner tube from being pulled completely out of the outer tube by external forces which would destroy the shock cell.
