Abstract: A mortise type lock has outside and inside mounting plates held in place on opposite sides of the door by use of screws accessible from the inside only. A decorative rose covers the outside mounting plate and an internally threaded outside sleeve which engages an externally threaded inside sleeve, in turn fastened to the mounting plate, overlies the rose preventing removal. The shank of an outside knob surrounding a rotatable sleeve has an aperture into which extends a spring pressed knob retainer for holding the knob on the rotatable sleeve. When the knob and attached parts are mounted on the mortise type lock a central spindle shifts from a position permitting release of the knob retainer to a position extending into the knob retainer to block movement of the knob retainer and release of the knob.
