Device for guiding long objects

A device for guiding a long object comprising a plurality of links, wherein the links are rotationally coupled together and form an accommodation space, which accommodates a long object, wherein:

• each link includes two link portions that are opposed to each other in a first direction and two arms that couple the link portions to each other,
• the links are rotationally coupled together while being arranged in series in a second direction perpendicular to the first direction,
• each link has a first end and a second end in a third direction that is perpendicular to both the first direction and the second direction,
• the link portions in each pair are coupled to each other by the associated arms at the first end and the second end of the associated link,
• the accommodation space is surrounded by the pairs of link portions and the arms and formed to extend in the second direction and accommodates the long object,
• a material of the link portions is a first material,
• two link portions that are adjacent to each other in the second direction are coupled to each other by coupling portions,
• the coupling portions are at least partially made of a second material having a wear resistance greater than that of the first material, and
• a space is formed between the two link portions over an entire circumference of the coupling portions.
