Abstract
A ring binder device for a file serves to hold documents and to provide a means whereby the file can be suspended spine uppermost between two carrier rails, the device having slide-mounted suspender members which can be set, by moving their slide mountings, to protrude beyond the edges of the file ready for resting on the rails, and the slide mountings incorporating locks operative when the suspender members are protruding to prevent the binder opening.
