Abstract
A quick-change picture frame, which for changing the picture has to be opened only at one corner and wherein miter cut elastic moldings are connected by a loosenable corner connecting piece at one corner and by firmly attached corner pieces at all other corners. Within the molding grooves are provided into which the edges of the corner pieces are fitted. The loosenable corner piece comprises a plate which is pivotably attached to the end section of one of the moldings, which form the openable corner, and has a guiding groove, which cooperates with a guide projection on the second molding of this corner in order to lock the corner piece when the frame is closed.
