An optical connector socket comprising: a body having a socket-side optical device installed therein and an insertion section to which a connected optical connector plug is inserted, a cover that is covered on the body and having a front frame section, the front frame section having an opening section communicating with the insertion section; a shutter openably and closably attached to the cover for closing the opening section and a helical spring that always elastically urges the shutter in a closing direction, against a back surface of the frame section; wherein the opening section is set to have an outside dimension greater than the outside dimension of the optical connector plug inserted into the cover and smaller than the outside dimension of the shutter; wherein the helical spring urges the shutter so as to bring all the periphery of the shutter into abutment with a back surface of the first frame section; wherein a pair of guide projections is provided at the inside of the insertion section of the body for guiding the inserted optical connector plug toward the socket-side optical device, and wherein a distance between the guide projections becomes narrower toward the backside of the insertion section.
