Abstract: In an arrangement for suspending a sheet member of a file folder or the like from a supporting rail having two longitudinal beads received in respective edge notches of the sheet member, the open side of one notch is normally obstructed by a unitary latch body movably secured to the edge portion of the sheet. Two bracket portions of the latch body receive the edge portion between respective opposite faces, a spring portion abuttingly engages the edge portion of the sheet member and biases the latch body toward an operative position in which a detent portion of the same obstructs the open side of the one notch.
