A coupling system including a male element having a first end and a second end in which the first end is integrally connected to said socket portion and said second end comprises an annular, circumferential shoulder. Also included is a hollow, pipe-like female element depending from the prosthesis to be changed, and having two longitudinal side openings each on opposite side walls of said female element. In association with the female element is a pair of cam latches which are rotatably secured within said side openings of said female element. Each cam latch comprises, in combination, a convex arc and handle element disposed, with relationship to said openings, such that the selective downward rotation of said handles will bring said convex arc of said cam latch into the interior of the female element and, thereby, within the walls thereof. The circumferential shoulder of the male element may be press-fittably inserted into said side opening such that said shoulders will be engaged by the selective downward rotation of said cam latches into and against the exterior of the male element. Therein, a prosthesis which is integrally secured to the first end of the male element may be readily connected or disconnected by the respective engagement or disengagement of the male and female elements.
