<p>The invention relates to a device for holding a film (20) carrying a picture to be projected, comprising a row of perforations (30) on each of at least two opposite edges. The device comprises two half-covers (half-mounts) (22) between which the film (20) is immobilised by penetration of conjugate projections (37, 39) and cavities (38, 41) which the two half-covers (half-mounts) possess, the said projections and cavities being arranged in correspondence with the perforations (30) of the film (20) in order for the said projections (37, 39) to penetrate into the said perforations (30) and thus hold the film (20) by its edges. <IMAGE></p> |
