A lock for grasping a keeper to lock a window sash and window frame together including a base housing with a longitudinal opening therethrough and defines a pivot axis positioned between the ends of the opening, and a locking handle secured to the housing for pivoting about the pivot axis and including a handle portion extending from the one side of the housing opening and a grasping portion extending from the other side of the housing opening. The housing has a first shoulder facing one side of the housing opening and extending about the opening associated with one end and a second shoulder facing the other side of the opening and extending about the opening associated with the other end. A first handle shoulder abuts against the first housing shoulder when the locking handle is in a locking position, and a second handle shoulder is disposed adjacent to and overlapping with the second housing shoulder when the locking handle is in a locking position. Preferably, the housing defines a substantially smooth visible surface facing the one opening side, with the first housing shoulder recessed relative to the housing visible surface; and the locking handle includes a substantially smooth visible surface substantially surrounding the handle portion and facing the one opening side when the locking handle is in a locking position so that the visible surfaces cooperatively define a substantially smooth visible surface surrounding the handle portion when the locking handle is in a locking position.
