Abstract: A cable protection cover includes a housing attachment section securing the cable protection cover to a housing of an electrical device and receiving an electric connector attached to the housing. The housing attachment section has a connector lock with a locking member restraining the electric connector in a pull-out direction in a position in which the electric connector is attached to the housing.

Abstract: 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).

Abstract: A ferrule (4) according to the invention for an optical fiber (1)is characterised in that the ferrule (4) is produced from plastics material and is welded on the optical fiber (1), which also consists of plastics material, preferably by ultrasound. The cladding (2) of the optical fiber (1) comprises depressions (3) which on welding also produce an interlocking fit in addition to the material connection.
