1. Mounting for a post (1) loosely mountable on a film bracket (7, 8, 22) with a retaining ring (13) taking up the post (1), the former being connected with the bracket (7, 8, 22) by means of a bayonet lock, characterized in that the retaining ring (13) is arranged direct in the bracket (7, 8, 22), and comprises several pins projecting radially in slots (12, 25) of the bracket (7, 8, 22) wherein the slots and pins mentioned above constitute the clutch elements of the bayonet lock, in that the slots (12, 25) open at the upper end form a flat angle at their lower ends with the horizontal line and that a flange part (15) of the retaining ring (13), its underside resting on the bracket, forms an abutment for a friction-type locking of the retaining ring (13) with the bracket (7, 8, 22). |
