A door latch operator mount comprises a coupling member and a bearing member. The coupling member includes a plurality radial flanges and an integral resilient arcuate tab member projecting angularly outwardly of the outer surface of the coupling member. The coupling member is mounted to a door for receiving the bearing member. The bearing member has an opening for rotatably receiving a shaft of the latch operator. The bearing member also includes a plurality of flanges and an arcuate channel which tapers in depth. When the bearing member is positioned against the coupling member, the distance of the bearing member flanges from the surface of the coupling member is less than the distance of the coupling member flanges form the surface. The tab member is received in the deeper portion of the arcuate channel. Upon relative rotation, a shoulder on the tab member seats in a notch in the shallower portion of the channel and the bearing member flanges are positioned between the surface of the coupling member and the coupling member flanges. The tab member is urged inward creating a force biasing the bearing member outwardly away from the coupling member and forcing the respective flanges against one another. The bearing member is thus secured to the coupling member and the latch operator is mounted to the door for operative connection to a latch retraction mechanism. A tool is provided for releasably engaging the bearing member enabling rotation of the bearing member relative to the coupling member.
