A handle for a window or door has a grip 241 rotatable relative to a casing 240. A stop member is received in the casing that can be moved between blocking and unblocking positions to allow the handle to move between open and closed positions. The stop member is moved using a push-button 246. The stop member may fit around the spindle 242, and prevent the spindle from rotating unless the push button is depressed. The stop member may be biased towards the blocking position using a spring. The spindle may have a cut-out portion 242a of smaller diameter than a blockable portion of the spindle. The blockable portion of the spindle may engage with a recess in the stop member (fig 19C). When the push button is used, the recess may be displaced from engagement thereby allowing the handle to move.
