Push bar fittings which extend in longitudinal grooves of the frames of windows, doors, or the like, are provided with holding means by which ribs projecting from the side walls of the groove are engaged from below, with the push bar being mounted for displacement above the ribs. To provide as wide a range as possible for cutting the push bar to length, and, on the other hand, to obtain a good guidance of the push bar ends in spite of that, the push bar is provided at the level of the ribs with a portion correspondingly sloping toward the groove bottom. Consequently, the free end of the push bar then extends in the groove portion below the ribs and is thus prevented from moving out of the longitudinal groove.
