PCT No. PCT/GB94/01980 Sec. 371 Date Mar. 11, 1996 Sec. 102(e) Date Mar. 11, 1996 PCT Filed Sep. 12, 1994 PCT Pub. No. WO95/07430 PCT Pub. Date Mar. 16, 1995An end fitting, particularly a pipe towing head, has an expandable element (44; 144) that is surrounded by a skirt (18) of a tubular body (14), so that a pipe end portion can be gripped between them. The element may have pipe gripping ribs which get less aggressive rearwardly, since the element is expandable by a mandrel (45) that leads to the greatest expansion at the rear. |
