The binding device (15) especially for the binding of loose sheets of paper (17) consists of a folded band of semi-rigid paper, quite concealing a common wire paperclip (10). The paper band consists of at least five planes (1, 2, 3, 4, 5) arranged in a row along the length of the paper band and separated by at least four parallel folds (6, 7, 8, 9). The first plane (1) has a length corresponding to the length of the shorter loop (12), the length of the third plane (3) corresponds to the length of the longer loop (11) of a common wire paperclip (10). The surfaces of the planes (2, 3) may be printed on the outer surface with a design for carrying a written or pictorial message for advertising, classified advertisements etc. The method of folding of the binding device (15) is executed thus, that a wire paperclip (10) firstly slides onto the first plane (1) by means of its shorter loop (12) in a direction perpendicular to the first fold (6), subsequently the first plane (1) is then folded to the second plane (2), which is folded across to the third plane (3), by means of which the folding of the paper band is completed from one side up the third fold (8). The paper band is then folded from the other, opposite end, whereby the fifth plane (5) is folded across to the fourth plane (4) and then the free end of the fifth plane (5) is tucked inside between the longer loop (11) of the paperclip (10) and the first plane (1) up to the third fold (8). Upon the last folding a V-shaped groove is formed.
