ABSTRACT:
A device for holding a removable accessory in position on the casing of a flashlight includes retaining members which project outwards from the front wall of the flashlight casing and are placed around an opening through which a light source is passed. The device is also provided with means for simultaneous radial displacement of the retaining members between a position of release and a position of clamping of the accessory by cooperation of the retaining members with the neck of the accessory, and elements for ensuring that the means employed for displacement of the retaining members are controlled through the intermediary of a ring disposed coaxially with the opening through which the light source is passed. The retaining members are guided with radial slideways.
