Abstract
A locking clamp assembly is provided, which can be expeditiously deployed on a drill pipe elevator or other tubular elevator, to secure the tubular elevator in a closed position around a tubular element, and can be rapidly removed to disconnect the tubular elevator from the tubular element. The locking clamp assembly includes a locking clamp having a main body defining a clamp space, which is sized and shaped to receive a pair of structural elements on respective jaws of the tubular elevator when the tubular elevator is in the closed position with the jaws of the tubular elevator extending around the tubular element. A clamp fastener may be secured to the main body to retain the structural elements within the clamp space. A tether may connect the main body to the tubular elevator.
