An optical connector comprises an optical fiber guide member consisting of a grooved substrate and a cover plate, the substrate having optical fiber guide grooves and guide pin grooves cut into its top surface, and the cover plate being joined to the substrate to cover the optical fiber guide grooves but to leave at least part of the guide pin grooves exposed; a pressing member which is movable in the vertical direction of the guide pin grooves and is provided above the guide pin grooves to elastically press guide pins which are positioned on the guide pin grooves downward; and coupling clips enhancing the force of elastic pressure being exerted on the guide pins so as to secure the joining of optical fibers.
