ABSTRACT:
An optic fiber inner tube connector includes an elongated tubular body having a central bore extending along a central axis and two threaded sections for engaging inner-threaded end caps. Each end cap has an inward flange having an inside diameter sufficient to allow the inner tube to extend therethrough. An axially movable retainer ring is provided between the flange of the end cap and the axial end of the body and having a circumferential channel spaced from the end of the body for holding therebetween a sealing ring which is deformable to sealingly engage the inner tube. The retainer ring catches to engage cavities formed on a deformable gripping member to fix the gripping member in the retainer ring. The gripping member is located between the flange of the end cap and the retainer ring, having an outside surface in wedging engagement with both the end cap and the retainer ring and an inside surface having teeth for catching the inner tube when the gripping ring is deformed inward due to the wedging force caused by the axial movement of the end cap. A resilient centering and sealing ring is provided inside the central bore, having an inclined face which radially centers the inner tube inside the body and hermetically seals the end of the inner tube when the end of the inner tube is forced into contact with the centering and sealing ring.
