A split sleeve 1 for optical connectors is provided, which may be constructed from a single part with a reduced cost and which permits retention forces on larger and smaller ferrules to be easily adjusted in uniform manner. The split sleeve 1 includes a cylindrical member made from a metallic material, such as phosphor bronze or stainless steel, representing an appropriate spring-back action. A slit is extended in the axial direction from one end to the other end of the cylindrical member. One end portion 1a of the cylindrical member on one side of an intermediate portion is configured to have a larger diameter, while the other end portion 1b of the cylindrical member on the other side of the intermediate portion is configured to have a smaller diameter.
