Abstract: Disclosed herein is an assembly in two parts with which to construct frames for pictures, prints and photographs, et cetera.The said two component parts are: a wooden or similar or plastic material strip that extends longitudinally and is essentially rectangular in shape, this having over the full length thereof a slit that is also rectangular; and an essentially V shaped body that can be elastically deformed and is provided with two U shaped limbs, each of which defines a tooth.With this particular assembly it is extremely easy both to insert the subject to be framed and to eventually replace it with another.
