A connection device for optical fiber includes a fastener for fastening two optical fiber ends (13, 25), a centering and guide element for centering and contacting the two ends, and a chamber filled with a cleaning product for cleaning the contact faces of the two ends of the optical fibers. The fastener includes, for each fiber end to be connected, a set of conical jaws (14, 21) suited to hold and to center an end, each set comprises has a face (19, 20) suited to be in contact with the other face so as to allow the two ends of the fibers to coincide along the same axis. At least one of the faces has at least one orifice communicating with a first chamber which contains a cleaning fluid, the chamber including a displaceable bushing (31) for emptying the chamber, the bushing being activated as the faces approach one another for contacting.
A connection device for optical fiber, comprising means for fastening two optical fiber ends, means for centering and contacting said two ends, means for cleaning the contact faces of the two optical fiber ends, characterized in that the fastening means comprise, for each fiber end to be connected, a set of conical jaws suited to hold and to center an end, each set comprising a face suited to be in contact with the other face so as to allow the two ends of the fibers to coincide along the same axis, and at least one of the faces comprises at least one orifice communicating with a first chamber which contains a cleaning fluid, said chamber comprising emptying means activated when said faces approach one another for contacting, wherein said emptying means comprise a piston displaced by the motion of one face approaching the other.
