<p>A fastening device for attaching a sheet (16) of flexible material to a support (12) and comprising a first part (10) mountable on the support (12) and a second part (14) engageable with the first part (10) characterised in that the second part (14) is attachable to the sheet (16) of material and is configured so as to be movable relative to the first part (10) when they are engaged, and in that the first part (10) is adapted to move relative to the support (12) whereby a force applied to the two engaged parts (10, 14) moving them in one direction relative to the support (12) causes the second part (14) to move relative to the first part (10) generally transversely with respect to said one direction.</p> |
