An optical connector (10) comprises a housing position correction means for correcting the relative displacement between the positions of plug and jack housings (13, 16); housing connection means (20, 22) so engaged with each other that the connected state of first and second optical fibers (11, 14) can be maintained, thereby connecting the plug and jack housings (13, 16) to each other; connection release means (26, 27) capable of releasing the connected state of the housing connection means (20, 22); and a frame position correction means for correcting the relative displacement between the positions of the frame (21) of an optical plug (12) and the connection block (34) of an optical jack (15).
