Abstract: A mounting element (12, 12a, 12b) for securing components, in particular profile bars, and a cap (14, 14a, 14b) for covering the mounting element (12, 12a, 12b) are provided. Indentations (31, 39) are provided in lateral ribs (22, 36) of the mounting element (12, 12a, 12b) and/or of the cap (14, 14a, 14b). This makes the grip better and/or facilitates aligning the mounting element (12, 12a, 12b) and/or the cap (14, 14a, 14b).

Abstract: A section rod is a component of a protective fence and serves for fastening a protective screen. A U-shaped receptacle, where the protective screen can be secured, is provided in the section rod. For this purpose, the receptacle has an internal width that is at least in part somewhat less than a thickness of the protective screen. An increased securing action can be achieved through additional sawtooth-shaped elevations. The section rod allows the protective screen to be mounted in a simple and reliable manner without additional fastening or securing parts.

Abstract: An angle bracket for joining two section bars has a relatively great stability, especially for use for partitions and safety walls. This stability is achieved by supporting walls that join the two legs of an angle bracket to one another and have an outwardly rounded outside contour. This design is relatively simple and inexpensive to implement and allows these angle brackets to be compatible with known designs.
