<p>A connection element 30 joins bars 10,20 of different diameter, the larger 20 of the bars being hollow in the region of the joint. The connection element 30 is circular, and conical with the greatest outside diameter equal to the inside diameter of the bar 20, and an inside diameter equal to the outside diameter of the bar 10. The connection element 30 is formed from four or six foam segments 32, with each segment 32 being covered with a fibre fabric tube 34 which is impregnated with resin. On curing of the resin, the tube sections between the segments form thrust walls 33. When the connection element 30 is used, another resin impregnated fibre fabric tube 40 can be stuck over the whole connection area.</p> |
