ABSTRACT:
A door latch lever handle fitting includes a retaining member which is pushed onto a shank portion of a lever handle. The retaining member has tongues which engage flats of the shank portion and tongues which engage in grooves formed in the surface of the shank portion to thereby grip the shank portion. In other embodiments where there are no grooves, different retaining members have modified gripping tongue arrangements. The retaining member is stressed to give axial thrust to take up any residual play in the assembly. Ears of the retainer member are engageable with an abutment lug on the rear face of a base plate of the assembly so that the door handle may be turned through a predetermined angle.
