PURPOSE: A window frame is provided to be fixed easily by using a corner connector and by cutting the corner of a PVC frame at an angle of 45 degrees.

Installing columns(4,4') are installed in both sides of a main body(3), and inserted in an installing groove(10) and a connecting hole(12). The main body is fixed on the cut-off face of the window frame. A connecting projection(6a) is projected from both sides of the installing columns, and assembled in the outside of a connecting column(13). An assembling column(5) is installed in the inside corner of the column(4), and a side-assembling column(5') is installed in the inside of the column(4'). Projected parts(6,6') are installed in the outside of the main body, and an inserting projection(7) is installed in the projected part to be assembled in an inserting hole(15).
