A ferrule ( 4 ) for an optical waveguide ( 1 ), according to the invention, is characterised in that the ferrule ( 4 ) is made of plastics material, and in that the ferrule ( 4 ) is for example more transparent than the casing ( 2, 3 ) of the optical waveguide ( 1 ). The process according to the invention, for fixing a ferrule ( 4 ) to an optical waveguide ( 1 ), includes the following steps: stripping certain regions of an outer casing ( 2 ) of one end of the optical waveguide ( 1 ) and exposing an inner casing ( 3 ) of the optical waveguide ( 1 ); pushing the ferrule ( 4 ) onto the stripped region of the optical waveguide ( 1 ); and welding the ferrule ( 4 ), at least in certain regions, onto the surface of contact with the inner casing ( 3 ) of the optical waveguide ( 1 ). Because of the transparency of this ferrule ( 4 ), the laser light can almost completely penetrate the ferrule ( 4 ) in the so-called transmission technique and take effect in the outermost region of the casing ( 2, 3 ) of the optical waveguide ( 1 ).
