An optical fiber cable holder (1) includes a holding member (2) and a fixing member (3). The holding member includes a top cover (21), a pair of holding arms (22) extending from opposite sides of the top cover, a pair of spring arms (23) extending from other opposite sides of the top cover, and a pair of locking hands (24) extending from the spring arms. A guide slot (211) is defined in the top cover, and a pair of receiving holes (213) is defined in the holding arms for retainingly receiving optical fibers (4) therein. The fixing member includes a base plate (2), an locking ring (32) connected with the base plate, and a locking groove (34) defined between the locking ring and the base plate. The locking hands are slidably received in the locking groove. The holding member is thereby rotatably engaged with the fixing member.
