A handle comprising a main body, a mounting seat formed integrally with the main body and disposed on the top thereof, and an adhesive tape coated with a bonding agent on both the upper surface and the underside. The mounting seat is soft and has a concave surface, so that the handle can be readily and positively affixed to the outer periphery of an existing doorknob by forcing the mounting seat thereagainst and clamping the same thereto after the adhesive tape is adhesively attached to the concave surface the mounting seat. The main body is flat in shape and has a rear edge which is inclined such that the main body is spaced apart a greater distance from the door in going downwardly from the top. A protuberance may be formed at the lowermost end of the inclined rear edge of the main body to form a finger holder.
