摘要

The barrier (3) has transverse beams provided with a round bolt interlocking unit (4a). The interlocking unit is guided into a round socket (5) that is inserted into a brickwork. The socket is fixed to a frame of a door (1) or window. The interlocking unit is fixed to a shoe that is movable on the transverse beams so that the barrier is adapted to a brickwork opening (2), where the transverse beams are provided with a recess. A round bolt interlock guidance unit (4) is attached to the shoe in an inner side. The socket has a semi-shell (6) that is provided outside the brickwork.
