A resiliently yieldable picture frame corner insert for use with a picture frame corner construction. The corner construction includes first and second elongate frame parts extending at right angles to each other and having juxtaposed end portions and longitudinal axes. Each of the end portions has a hole therein extending perpendicular to the longitudinal axis of the frame part and a slot extending from the hole and through the end portion. The corner insert is secured to the juxtaposed end portions for retaining them in contact with each other. The corner insert is formed as one piece and has first and second web portions disposed in the slots and first and second outer portions disposed in the holes. The web portions are resiliently yieldable with respect to each other and serve to apply yieldable forces tending to urge the juxtaposed end portions into engagement with each other. The first and second outer portions are enlarged with respect to the web portions and have forwardly tapered end portions which extend beyond the length of the web portions and are adapted to facilitate insertion of the corner insert into the end portions. In one embodiment, the first and second web portions extend in respective planes which intersect at an angle ranging from 80 DEG to 95 DEG and are tapered in cross-section in plan in a direction toward the outer portions.
