Abstract: An assistive device for a door having a door lock mounted adjacent to a doorknob. The door lock is rotationally actuatable via a thumb lever. The assistive device comprises a handle adapted to mount on to the thumb lever without obstructing the doorknob and a mounting slot formed between opposed ends of the handle for forming a frictional fit between the handle and the thumb lever. The handle includes an elongated end configured to provide leverage for rotation of the thumb lever using the handle, and an arcuate end for grasping. The mounting slot at least partially surrounds the thumb lever in a plane of rotation thereof.
