Abstract

A self-locking clip for a picture frame that is formed with a channel. The clip comprises an elongate piece of spring steel whose longitudinal end is bent to define a planar shelf from which depends a leg which defines an edge that is adapted frictionally to engage the inside surface of the channel and when the planar shelf is depressed, the edge is released from the inside surface of the channel to allow the clip to slide relative thereto.
