KNOB ATTACHMENT FOR DOOR LATCH ABSTRACT OF THE DISCLOSURE A door latch makes use of moldable material for most of the individual parts with opposite roses adapted to interlock with each other and be held together with a single screw on the axial center line of the knob and ac- cessible from the outside. Prior to installation of the latch on the door, each knob is subassembled with the cor- responding rose by employment of an arcuate shoulder on an inner central portion of the knob which is rotated to a position of engagement with a complementary arcuate shoulder in in the rose. Rotation inhibiting detents prevent accidental disassembly until the spindle is mounted in place and the spindle then locks the knob against disassembly as long as the latch remains mounted on the door.
