ABSTRACT:
Apparatus for coupling the axial extremities of two associated inner ducts used for housing at least one fiber optic cable. The coupling includes first and second cylindrical sections, each having inner concave faces and outer convex faces and apparatus for engaging the axial extremities of the associated inner ducts. The apparatus for engaging is disposed on the inner face of the cylindrical sections. The apparatus also includes structure for providing mutual gripping between the first and second cylindrical sections. The structure for mutual gripping on the first and second cylindrical sections is disposed on the first and second cylindrical sections and functions only when the first and second cylindrical sections are engaged with at least one axial section of an inner duct.
