The cone and an integral cylinder project coaxially from the base of the cone. A sleeve is slidable onto the cylinder and detents latch the sleeve on the cylinder. An elastic ring which is for contracting on the penis to maintain an erection, is expanded by sliding it over the cone until it slips onto the sleeve. - The sleeve is unlatched by twisting it to depress the detents and is slipped off of the cylinder with the elastic ring on it. The sleeve with the ring on it is slipped to the base of the penis and the ring to slide off for contracting. (2/8)
