A pre-fitted optical fiber section (2) is held in a plug ferrule (1) in such a way that it extends from a face (3) up to a lateral fusion access aperture in the plug ferrule (1). From the direction of an entry surface (7) at the cable-end, a bore (6) running coaxially to the optical fiber section also leads into the fusion access aperture. Within the fusion access aperture, the pre-fitted optical fiber section can be welded to the optical fiber (27) of an optical fiber cable (24) in the field. The plug ferrule is assembled from at least two components, of which one (8) possesses the outer jacket serving to center the plug ferrule and the other (10) possesses the fusion access aperture (4) and the bore (6). Both components comprise differing materials, which considerably facilitates manufacture.
