An optical fiber connector adapted to use with two optical fibers includes a base seat, a positioning member, and a joint unit. The base seat includes a tubular wall defining an axial hole and two extension walls defining an accommodation space in spatial communication with the axial hole. The positioning member is disposed in the axial hole and defines a channel permitting the optical fibers to extend therethrough. The joint unit includes two central pins and two sleeves. The central pins are adapted to be connected respectively to the optical fibers. The sleeves are sleeved respectively on the central pins and are detachably mounted to the base seat such that positions of the central pins relative to each other are fixed.
