1. An optical fiber connector and cable assembly including an optical fiber cable and an optical fiber connector, the optical fiber cable having an optical fiber and a cable sheath, a free end of the optical fiber being provided with a ferrule, the ferrule being associated with a ferrule spring, wherein the optical fiber connector comprises:
a connector body and a cover connected to a proximal section of the connector body, the cover and the proximal section of the connector body defining a proximal chamber;
a first fixing sleeve placed onto the optical fiber cable and a second fixing sleeve placed onto the first fixing sleeve; and
an insert directly connected to a distal end of the first fixing sleeve having a passage for receiving a proximal section of the ferrule and supporting the ferrule spring;
wherein the first fixing sleeve, the second fixing sleeve and the insert are received in the proximal chamber, and
wherein, in a direction facing a distal end of the connector body, the cover presses the first or the second fixing sleeve, the first fixing sleeve presses the insert, the insert presses the ferrule spring, and the ferrule spring presses the ferrule.
