摘要
The invention relates to a protective device (1), in particular for a ventilation system, comprising at least one protective element (3) that has an elongated, twisted profile (9) having a polygonal cross-section or is a round tube, wherein the geometric configuration of the protective element considerably reduces the installed mass, such that a weight reduction is achieved owing to saving of material.
