A locking mechanism for a slidable door or window. The mechanism having a catch (4) which is manually adjustable in the direction of sliding of the door/window, by means of ratchet teeth (6) clamped in position by a bolt (7), to ensure that the door/window is locked tightly in place when the latch is in the engaged condition. Independently, the mechanism comprises a two part socket (16,17) resiliently biased away from one another so as to absorb any impact between the catch (4) and socket. Independently also, the catch (4) is provided on a slider (3) which, when the catch is in its locked position, prevents vertical movement of the door/window and also prevents the catch from being moved away from the locked position until the slider is depressed against the action of a spring. The slider is locked in the engaged condition by the engagement of a lower flange (11) with a stop (10) under the biass of spring (13). |
