The invention relates to a clip for clipping together sheets which are made of paper, plastic, metal etc, on the corners or sides thereof. Said clip is U-shaped and comprises two similar or different limps. The stack of paper is clipped together between said two limps or by means of projections incorporated therein. The invention is characterised in that said clip is embodied as a triangular single piece or is trapezium-shaped or is shaped like a semi-circle or is semi-elliptically shapes with limpbs (1, 1a or 1b) which are arranged parallel to each other when in the rest position. The two limbs (1, 1a or 1b) comprise a small fold (3), which is inwardly curved an which bends to form an acute or obtuse angle (3a), on each side (4) forming an acute angle or an obtuse angle (4a) with the back (2) or on each vertex (8). The two limbs (6) are arranged on top of each, parallel to each other and are connected together without mutual contact by means of a spring (7) both in a rest position and also in a position wherein a stack of sheets is clipped. The clip is displaced in the direction of the edge (4) or the back (2) on the stack of paper and is clipped by the pre-tensed back (2) or the spring (7) on the folds (3) which are inwardly curved. |
