A scaffolding (20) comprises vertical frame elements (22), crossbeams that extend therebetween, flooring units (27) which have mounting aids (28) to be mounted on the crossbeam (21), and at least one anti-release device (40) for securing the flooring units (27) against being released. The anti-release device (40) can be removably connected to the crossbeam (21) and has a securing member (41) which corresponds to the length of the crossbeam, is to be placed on the mounting aid (28), and is fitted with at least one hook-shaped fastening element (42) that penetrates a hole (33) located in the crossbeam and partially embraces the crossbeam (21) in the anti-release state. One end of the securing member (41) is provided with a pivotable plate which is fastened by means of a hinge and is pivoted from the open position into the locking position and retained by means of a spring mechanism (60). Alternatively or additionally, the hook-shaped fastening element (42) can be made of flat steel, and the parallel lateral surfaces are placed at an adequate distance from the mounting aids (28) in the anti-release state in order to prevent a collision.

1. Scaffolding having: at least one crossbeam that extends between two vertical frame elements and connects these with one another;at least one flooring unit that has at least one mounting aid for mounting the flooring unit to the crossbeam; andat least one anti-release device for securing the flooring unit against release from the crossbeam, which anti-release device is releasably connected with the crossbeam and has: a securing body to be laid onto the at least one mounting aid, which securing body has at least one hook-shaped fastening element that, in the state in which it is secured against release, engages through a hole provided in the crossbeam, and at least in part behind the crossbeam,a plate attached by a hinge at one end of the securing body, which plate can be pivoted from an open position in which it allows both installation and removal or release of the anti-release device into a closed or securing position, in which the flooring unit is secured against release from or out of the crossbeam, whereby the length of the securing body including the plate approximately corresponds to the length of the crossbeam, anda plate securing aid that comprises a spring for at least one of pivoting the plate from its open position into its closed or securing position and holding the plate in its closed or securing position,wherein the spring is a helical spring which is formed as a double leg spring composed of a first leg spring and a second leg spring, which comprises, in each instance, a first leg and a second leg,wherein the first leg of the first leg spring and a first leg of the second leg spring are formed in one piece and form a common v-shaped or u-shaped leg,wherein at least one of the plate and the securing body has a first stop body to prevent over-stretching of the spring during pivoting of the plate from the closed or securing position into the open position,wherein the first stop body is formed in one piece with at least one of the plate and the securing body,wherein the first stop body engages at least in part around a pivot axis of the hinge,wherein the plate, during its pivoting from the closed or securing position into the open position, makes contact against or with the first stop body at an angle of inclination, relative to a plane that is spanned through the securing body and contains the longitudinal axis of the securing body, which angle of inclination is at least one of greater than zero degrees and such that the plate is not pivoted completely against or onto the securing body,wherein at least one of the plate and the securing body has a second stop body to limit pivoting of the plate in the closing direction, into a position that allows simple assembly, andwherein the second stop body engages at least in part around the pivot axis of the hinge. 2. Scaffolding according to claim 1, wherein at least one of the first stop body and the second stop body is configured as a stop nose or a stop tongue. 3. Scaffolding according to claim 1, wherein the second stop body is formed in one piece with at least one of the plate and the securing body. 4. Scaffolding according to claim 1, wherein the first stop body of the plate and the second stop body of the plate are formed from the plate so as to extend in different directions from the plate, or wherein the first stop body of the securing body and the second stop body of the securing body are formed from the securing body so as to extend in different directions from the securing body. 5. Scaffolding according to claim 1, wherein in the closed or securing position of the plate, the first stop body extends to above a plane spanned through the plate, and wherein the second stop body extends to below the plane spanned through the plate. 6. Scaffolding according to claim 1, wherein the plate, at least in the non-installed state of the anti-release device, has force applied to it in the closing direction by the spring force of the spring, in such a manner that the plate makes contact on or with the second stop body, at an angle of inclination, relative to the securing body or to a plane spanned through it and containing its longitudinal axis, which angle is greater than 135 degrees and is smaller than 225 degrees. 7. Scaffolding according to claim 6, wherein the angle of inclination is greater than 170 degrees and smaller than 205 degrees. 8. Scaffolding according to claim 1, wherein the hook-shaped fastening element comprises solid material. 9. Scaffolding according to claim 1, wherein the hook-shaped fastening element is produced in a manner free of edging or bending. 10. Scaffolding according to claim 1, wherein the crossbeam is attached to one of said frame elements using a fastening body formed with or from flat material, and wherein a face side of a free end of the securing body is provided with an oblong recess that extends in the axial direction, for accommodating the fastening body, and wherein the face side of the free end of the pivoting plate is provided with a similar or identical recess, whereby the recess and the similar or identical recess are configured, in each instance, as a slit, which is delimited by parallel slit walls, which have a distance from one another that corresponds to the slit width, which is of the same size or only slightly greater than the thickness of the flat material of the fastening body, so that if only on one side of the crossbeam, at least one flooring unit is mounted in or on it with its at least one mounting aid, the anti-release device is canted on the flat material of the fastening body, in such a manner that it is not tilted about its longitudinal axis. 11. Scaffolding according to claim 10, wherein the slit width is maximally 25% greater than the thickness of the flat material of the fastening body accommodated in the slit.
