A removable handle for use with a wheelchair having two handles includes a handgrip crossbar which has two ends, two support posts, each of which is hollow and has a wall, and two connectors. The handgrip crossbar is coupled to one of the two ends of the handgrip crossbar in spaced parallel relation. Each connector connects one of the handles to the other end of one of the support posts. Each connector is cylindrical and has a first end, a second end and a wall. The connector is fixedly coupled to one of the two handles. The connector is slidably and detachably coupled to one of the support posts. Each support post has a hole in the wall. The connector has an inner surface with a groove adjacent to its first end. The connector also has a flat spring and a disc. The flat spring is disposed in one of the support posts. Each disc is fixedly coupled to one of the flat springs and is inserted in its hole. When each support post is inserted into one of the connectors, the groove securely engages the disc.
