A picture frame member for use in assembling a picture frame incorporates a flip-up type clip for the releasable independent retention of a picture and backing board. Each member consists of an elongate flat base, a clip comprising a generally channel-shaped elongate member having two flanged edges facing the base, a downwardly-biased clip support extending along an edge of the base, and a hinge that links the clip to the clip support. The two flanges of the clip separately grip a picture and a backing board. There may also be provided a separate backing board grip member incorporated into the base. The clip employs an over-centre mount to the clip support, in order to permit the clip to maintain either a flipped-open position or a closed position wherein an increased grip pressure is applied to the backing board in relation to the picture."
