Abstract: The safety system is usable for a container for photographic products in strip form wound on cores which container comprises a substantially horizontal cantilevered spindle having a free end and designed to support the cores and a door which can be located on the spindle by a locating device. The safety system comprises, at the free end of the cantilevered spindle, an element able to move between a first position of rest in which the element does not project beyond the volume delimited by the cylinder of revolution generated by the internal diameter of the cores and prevents the closure of the door, and a second position of rest in which the element projects beyond the volume delimited by the cylinder generated by the internal diameter of the cores in order to prevent the cores from leaving the spindle and releases the locating device so as to allow the closure of the door.
