The structure forming a network of links, consists of several interconnection pieces (1) forming link nodes and several tubular elements (2) interconnecting the interconnection pieces. The tubular elements are provided at each of their ends with a joining piece (3) designed to cooperate with the interconnection pieces. The joining pieces are joined at the ends (20) of the tubular elements by a method of pivoting. Also the interconnection pieces contain several longitudinal slots (12) into which the end lip (34) of the joining piece can engage and be anchored by a spring loaded blocking piece (310).
