Abstract

The key locks the shuttering flanges together after axial penetration follow by half turn rotation, being retained by an attached pivotably retractable spring clip (6). Comprising a round section shaft (1) with a truncated arrowhead (2) at one end, the key inc a slidable washer (16) with three alternative diametric shaft holes locating a fulcrum pin (11) for the clip. The head provides diametrically opposed radial shoulders (3) which provide a prim clamping face, the counter face being provided by the washer under clip pressure. The head may be rectangular in axial profile, the length of the least side equalling shaft dia, all faces (4, 5) being inclined towards the tip.
