Abstract
A film cassette comprises a pair of housing parts, and a flexibly movable latching hook located on one of the housing parts and a rigid latching catch located on the other housing part which can engage to secure the two housing parts together. According to the invention, a backer projects from one of the housing parts into abutment with the latching hook, when the latching hook and the latching catch are engaged, to prevent the latching hook from moving out of engagement with the latching catch in response to a mechanical shock being applied to the film cassette.
