Connecting part for an optical connection and method for connecting two optical fibers

A connecting part for an optical connection of a first optical waveguide to a second optical waveguide comprising:

• a sleeve-like cable holder containing a first cable holding section in which the first optical waveguide is capable of being held;
• and
• a second cable holding section in which the second optical waveguide is capable of being held, wherein the optical waveguide ends of the two optical waveguides are weldable to one another, with at least the second cable holding section being designed such that it is joinable together along the longitudinal center axis, wherein the second cable holding section has at least one casing part which is pivotable on a joint through a specific pivoting angle between an open position and a closed position, wherein attachment means are provided on the first cable holding section with aid of a covering sleeve, which is capable of being fitted from the second cable holding section, and is attachable to said attachment means in order to cover the cable holder.
