Embodiment Construction

[0025] Referring first to Figures 1A and 6, there is shown a device for retaining a stack of paper in a folder. The device comprises a base 10 made of pressed steel sheet with holes 12 for receiving rivets (not shown in the figures) to fix the device to the folder. Protruding from the base 10 are two rings 14 each comprising a fixed post 16 and a movable arch 18 . The post 16 passes through a hole 19 (see FIG. 6 ) in the base 10 and is secured to the base 10 by forging the bottom end of the post to deform it.

[0026] Said arched parts 18 of the two rings 14 are connected together by an intermediate part 30 which is pivotably mounted to the base by means of two curved arched tabs 31 (see FIG. 6 ), said The web 31 is pressed out of the base 10 . Such an arrangement enables the arched part 18 and the connecting part 30 to rotate about a horizontal axis 25 extending between the two tabs 31 .

[0027] The connecting part 30 has a crank part 32 . One end (34') of a leaf spring ...
