A quick-assembly picture frame is provided with improved means for locking the precut frame members together. The invention is intended for use primarily with picture frames formed from metal in extruded cross sectional shapes. Adjacent ends of frame members which define the corners of the frame are locked together by L-shaped brackets which are received in channels at the rear face of each of the frame members. The L-shaped brackets at each corner are secured to the channels by any suitable means such as screws which bear inwardly toward the bottom of the channels to secure the L-shaped brackets in the channels. The L-shaped brackets and channels are formed in a manner which, when the screws are tightened, will cause adjacent frame members to pivot slightly about their lengths and in a manner which draws the forwardly facing corner regions of the frame sections tightly together.
