The invention relates to a clamping device (1) for fastening a surface-covering object (2) such as a tarpaulin, a banner, a sheet or similar, comprising: a base element (3) provided with an insertion passage (4), a clamping portion (6) extending in a first direction from said insertion passage (4), said clamping portion (6) being provided with a patterned engagement surface (8), and an eyelet portion (9) extending in an opposite direction from the insertion passage (4), said eyelet portion (9) having an opening (10) adapted for engagement with an outer fastening means (11) such as for example a draw-string or a hook member, a wedge-element (12) adapted to insertion into the insertion passage (4) of the bas element (3) in order to effect a clamping of the object (2) between a lower face (13) of the wedge-element (12) and the clamping portion (6), said wedge-element (12) having an eyelet opening (20) which substantially overlaps the eyelet opening (10) in the eyelet portion (9) of the base element (3) when the wedge-element (12) is inserted in the insertion passage (4). The invention is particularly characterized in that an interstitial element (23) for use when clamping a relatively thin object (2), is releasably attached upon the clamping portion (6) of the base element (3) in such a way that the lower face (13) of the wedge-element (12) partly abuts an upper face (7) of the interstitial element (23) whilst the object (2) abuts a lower face (24) of the interstitial element (23) and the patterned engagement surface (8) on the clamping portion (6) of the base element (3), the wedge-element being adapted to slide on the upper face (7) of the interstitial element (23) during a progressing clamping phase. |
