An optical fiber connecting device in which a pair of ferrules holding optical fibers in their central holes and opposing at their end faces are inserted in a through bore of an aligning sleeve having a structure that enables the angles of the ferrules' end faces at which they contact each other to be adjusted by rotating both or either of the ferrules, and enables the adjusted positions to be fixed. A pair of optical connector plug assemblies each include a ferrule having an optical fiber-holding central hole and a threaded portion formed at one end of its outer-diameter portion, a cylindrical position-determining ring having a threaded hole rotatably engageable with the threaded portion and a position-determining key provided on its outer-diameter portion, and a ferrule-urging compression coil spring and a threaded-hole-provided engagement nut which are slidably fitted around the outer-diameter portion of the ferrule. An aligning sleeve has keyways formed at either end of its outer-diameter portion and is adapted to receive the position-determining keys, threaded portions formed at either end of the sleeve's outer-diameter portion and adapted to engage with the plug assemblies, and an aligning through bore formed in the central portion of the sleeve to allow the ferrules' leading end portions to be inserted therein from either ends and to oppose each other.
