Abstract

A handleset includes a housing, a spindle sleeve, a handle, a coupler, and a spindle. The spindle sleeve includes an aperture, and is rotatably mounted to the housing. The handle is mounted to the spindle sleeve and includes a recess aligned with the aperture. The coupler is movably mounted in the aperture for movement between a decoupling position and a coupling position. The coupler in the coupling position is disengaged from the recess and does not prevent removal of the handle from the spindle sleeve. The coupler in the coupling position extends into the recess and prevents removal of the handle from the spindle sleeve. The spindle is movably received in the spindle sleeve and selectively retains the coupler in the coupling position.
