An optical fiber connector includes a housing and a clamping element. The housing defines a receiving space including an inner bottom surface. The inner bottom surface defines first grooves and first receiving grooves aligned with the first grooves, and includes two clamping holes. The clamping element is received in the receiving space and includes a cantilever beam and two hooks extending from the cantilever beam. The cantilever beam includes a bottom surface defining a second receiving grooves. The two hooks are received into the two clamping holes to fix the clamping element to the housing. The first receiving grooves and the second receiving grooves cooperatively define receiving holes to receive optical fibers.
