Abstract
A cable grip device, known as a 'stopper', suitable for holding submarine cables during laying and recovery operations on board a ship, comprises a conventional helically wound stopper modified to have a low coefficient of friction over an internal surface portion (1A) and a higher coefficient of friction portion over a surface (1B), which it is found enhances the tensile load which the stopper can bear particularly when used for smooth surfaced deep water submarine cables.
