A locking window. The window includes a window frame including a window sash which is selectively movable between a first closed position and a second open position. A window latch is adapted to be attached to the window and is selectively movable between a first open position and a second locked position to secure the window sash in the closed position. The window latch includes a sweep latch, which is preferably offset, and a non-compressible pivot fastener for attaching the window latch to the window. The offset arrangement provides sufficient space for substantially unequal length actuator and locking arms to provide a mechanical advantage when the window latch is operated. The pivot fastener includes a support bushing and a fastener extending through the support bushing for attaching the offset sweep latch to the window. In the preferred embodiment, the base of the support bushing extends outward to form a load distributing surface and the distal end of the support bushing extends above the surface of the offset sweep latch to allow the offset sweep to move freely about the pivot fastener. A housing extends beyond the pivot fastener parallel to the window frame and includes an aperture for receiving a fastener for attaching the housing to the window. A portion of the housing extending beyond the pivot fastener parallel to the window frame may include a finger well for providing access to the offset sweep latch. In the preferred embodiment, a detent retains the offset sweep latch in its open and locked positions and also provides an audible indication of the position of the offset sweep latch.
