An optical fiber connector includes a housing, a ferrule, a bias member and a flexible tube. The ferrule is formed with a first axial hole of a first inner diameter larger than an outer diameter of a jacket of an optical fiber and a second axial hole that is communicated to a distal end of the first axial hole and that has a second inner diameter smaller than the first inner diameter and larger than an outer diameter of a fiber wire of the optical fiber. The flexible tube is inserted around the proximal end side of the ferrule so that at least a part thereof is extended toward the proximal end side than the ferrule to form a proximal-end-side extended part. The proximal-end-side extended part has an inner diameter larger than the outer diameter of the jacket and smaller than the first inner diameter.
