ABSTRACT OF THE DISCLOSURE A portable security grill apparatus (10) which may be installed in window openings of buildings includes two rectangular grill sections (19, 20) longitudinally telescopically fastened to one another. Opposite longitudinal ends of the two grill sections have base and roof plates (16, 21) disposed perpendicularly to the axis of longitudinal telescoping bars (12, 23) of the two grill sections, the plates supporting beams (17, 22) having flat outer surfaces adapted to abut the window edges at each end of the grill apparatus. At least one toggle clamp (24) is connected between telescopically joined members of the two grill sections and the clamp exerts a large outward extension force when it is moved into a closed, clamped configuration, thereby exerting compressive forces on the window and window frame sufficient to prevent the grill apparatus from being removed from the window opening.
