<p>A tamper resistant seal comprises a series of ratchet teeth (12) arranged along a strap (14), with one end of the strap (14) being secured to a body (16) and the other end of the strap (14) being insertable into the body (16) to move the ratchet teeth (12) sequentially past a resiliently deformable catch (18), characterised in that the resiliently deformable catch (18) includes a pair of opposed jaws (44) which are movable laterally primarily with a vice-like action (spreading) rather than a collet-like action (flexing). <IMAGE></p> |
