ABSTRACT:
A integral plastic frame for holding a film slide includes a central window, a recessed bearing surface, which surrounds the window and serves to contact the film slide when it has been inserted to cover the window. The transparency as it is inserted and in its final position is guided between the bearing surface and the retaining elements facing the bearing surface. The retaining elements substantially consist of continuous retaining strips, which extend in the direction in which the film slide is inserted. The retaining strips are attached to mutually opposite sides of a central window of the integral frame member by means of narrow connecting webs, which extend at right angles to the direction in which the film slide is inserted. The plastic material of the frame member is so elastically flexible that an opening through which the film slide can be inserted is formed between the retaining strip and the bearing surface.
