A connection socket for detachably connecting distal ends of different, thin and thick, endoscopes light guides to a single light source device includes a socket block with a cylindrical aperture accepting a distal end of a light guide in an axial direction and retainer plates pivotally mounted within the socket block around the aperture for holding and retaining a distal end of an inserted light guide, each retainer plate having a peripheral edge facing the aperture that includes first and second retaining edge sections. With a thin light guide, the retainer plates retain the distal end with the first retaining edge sections. When a thick light guide is inserted within the aperture, the retainer plates are pushed and turned by a distal edge of the thick light guide, bringing the second retaining edge sections into close contact with the distal end, retaining the distal end of the thick light guide.
