A film retaining insert for reels comprises a unitary molded insert that is provided with either a slot or a slot and pin arrangement capable of anchoring the end of a strip of film to facilitate winding film from or onto the hub of the reel to which the insert is secured. The insert is shaped to fit within the space between the axis and the hub of the reel, and has an entry slot adapted to register with a threading slot extending transversely through the hub of the reel. The end of a strip film to be wound on the reel is threaded through the threading slot and into the entry slot of the insert, and then anchored thereto. The insert holds the film end firmly against accidental displacement from the reel, and thereby facilitates winding the film from or onto the hub of the reel.
