Abstract
Abstract The crimp splice serves the purpose of connecting light waveguide fibers which are fixed by radial pressure. For this purpose, the light waveguide fibers are placed in a guide channel in the base surface or area of, for example, an outer part, are pressed against one another, and are fixed by a clamping action between an inner part and the outer part. A required pressing power for the clamping is achieved by pressing legs of the two parts together. The crimp splice is simple to produce and permits easy assembly.
