A structure has components (2, 4) which are linked by a push-fit ball-and-socket (6) fitting. The ball (32) is an extension of an upright shank (34) bolted to a fixed sub-structure (4). The socket (6) is an elastomer linked to a surrounding cylindrical support by an S-shaped cross-piece. The elastomer is a plastic material. |
