A built-in lock for a window with a leaf with a front wall and a fitting groove along a periphery of the leaf of the window with at least one locking slat that is slidable in said fitting groove, the built-in lock enabling operation of the at least one locking slat, whereby the built-in lock comprises:

• a handle with a lever and a spindle with a rotational axial direction;
• an operating mechanism for converting the rotation of the spindle around its axial direction into a translation of the at least one locking slat and a base that is separate from the handle and which is provided with a passage for the spindle of the handle,
• wherein the operating mechanism comprises a clamping plate for holding the operating mechanism on the leaf by means of clamping means allowing clamping of the clamping plate and the base together with inclusion of the front wall of the leaf,
• whereby the clamping plate is provided with a bearing for the rotation of the spindle,
• whereby the bearing is held fast in the clamping plate in the axial direction
• whereby the bearing is provided with a clip mechanism to lock the spindle in the axial direction with respect to the bearing the bearing being affixed freely rotatably in a seat of the clamping plate,
• whereby the bearing is comprised of a dish and a slider with a passage for the spindle of the handle and
• whereby this slider is movably affixed in the dish and biased in a biasing direction transverse to the axial direction of the spindle, enabling the slider to engage with a notch in the spindle of the handle in order to lock the handle in the axial direction.
