The invention concerns a linking piece designed to maintain a spacing between at least two anchoring elements screwed into vertebrae. The piece comprises at least: a flexible part (10) divided into two branches (12, 14), the ends of said branches being interconnected in pairs and defining a first neutral plane (Pm), and, two rigid parts (20, 22) forming rods, having a first fixing C portion (20', 22') and a second fixing portion (20'', 22''), each said second portion (20'', 22'') of said rigid parts (20, 22) extending respectively in two opposite directions said ends of said branches interconnected in pairs, such that said linking piece, whereof the fixing portions (20', 22') are respectively fixed on each of the anchoring elements is designed to bend elastically perpendicularly to said neutral plane (Pm).
