<p>A nose portion (21) (or an end cap (9)) of a stay (1), comprising a weakened region (39) which, when subjected to a force, greater than a predetermined force, acting to open a vent (not shown) mounted on the stay (1), in use, collapses to expose a protrusion (37) which engages the end cap (9) (or the vent arm (7)) of the stay (1) to resist further opening of the vent. Such a nose portion (or end cap) can help to prevent unauthorised opening of a stay. <IMAGE></p> |
