A handle for a window operator. The handle includes a handle member 10 pivotally coupled to a base 11. A locking mechanism releasably locks the handle member 10 in a position relative to the base 11 which corresponds to an in-use position of the handle member. The locking mechanism includes a locking member 14 within the handle member 10. The locking member 14 performs a blocking action to prevent pivotal movement of the handle member relative to the base. The locking member has a push button 15 accessible to an exterior surface of the handle member whereby the locking member can be moved to remove the blocking action and allow the handle to be pivoted to a non-use position.
