OPTICAL CONNECTOR, HOUSING FOR OPTICAL CONNECTOR, AND METAL CASE FOR OPTICAL CONNECTOR

Provided are an optical connector, a housing for the optical connector and a metal case for the optical connector, by which the metal case is fixed to the housing with no need to push outward free ends of side plates of the metal case, so that the metal case is prevented from being shaky and thus has an improved strength, which stabilizes a connection state of optical transmission path-related members and also allows high quality transmission characteristics to be maintained for a long time. A metal case 14 has engageable concaved parts 142 at free ends of side plates 14b. A female connector housing 13 has engageable convexed parts 130, engageable with the engageable concaved parts 142, on side surfaces 13b corresponding to the side plates 14b of the metal case 14. The engageable convexed parts 130 have separation restriction parts 130a for restricting the side plates 14b from being laterally distanced from the side surfaces 13b in a state where the engageable convexed parts 130 and the engageable concaved parts 142 are in engagement with each other.
