Telescopic protective covering

A protective covering comprising:

• a plurality of substantially L-shaped protective covering segments, each covering segment having a cover leg and a support leg, said covering segments being telescopically slidable with respect to one another, wherein the cover legs of adjacent protective covering segments respectively come to bear on one another thus forming a substantially closed surface;
• at least one flexible connecting element connecting the support legs of the protective covering segments with each other so as to at least transfer a tensile force;
• and
• at least one elastic reset element having a first terminal end and a second terminal end, said first end fastened to the support leg of one of the plurality of covering segments and said second end prestressing directly against a section of the at least one flexible connecting element, pushing said section in a direction of the support leg, such that a momentum is induced onto the protective covering segment by the connecting element via the reset element arranged on the support leg, the momentum leading to telescopic overlapping of the covering segments.
