Abstract
A handle for a door, window or other openable structure. A handle body 8 is rotatable about the axis of a spindle 14. A spindle-engaging part 2 is manually movable along the handle body 8 and into and out of engagement with the spindle 14. Thus, rotation of the handle body 8 causes rotation of the spindle only when the spindle-engaging part 2 engages the spindle 14. A catch 24 retains the spindle-engaging part 2 in its engaged position.
