PROBLEM TO BE SOLVED: To provide a connecting device for a picture frame corner, by which the connection of corners are not destroyed even when twisting direction force is added to both frame materials which are connected in the corner of a picture frame. SOLUTION: This device is provided with fixing arms 2a and 2b which are opened by prescribed angle to be inserted to the both frame materials F1 and F2 abutted in the corner from the abutment ends F1' and F2' of the frame materials F1 and F2. Elastic arms 3a and 3b which are extended from each tip side of the fixing arms and are provided with projections 4a and 4b to be engaged with the holes H1 and H2 of the frame materials are arranged. Structures 5 are disposed over the tip parts of the fixing arms and the tip parts of the elastic arms. Then the elastic arms extended from the tip surfaces of the fixing arms are not deformed even when twisting direction force is added to the both frame material F1 and F2 which are abutted in the corner.
