The lock bolt (13) is operable via an aperture (17) in the housing (10) into or out of engagement with a closure plate (23a) in the window or door frame (23). The lock housing has at least two seats (18,19) for a stop head (16) pivotably connected to the bolt (13). The stop head can be pivoted outwards through the aperture (17) from a stop position in one of the seats to an angle position which deviates from the bolt longitudinal axis in the channel. It permits movement of the bolt into or out of engagement with the closure plate. |
