An extensible chain, essentially characterized by being made up of pairs of pieces or bodies of which those corresponding to a link, by means of the game offered by a small punch that joins them at their central part, are movable as scissors, and by the existence of a small spring disposed inside the rivet which, when the links of the chain are distended, tends to return them to their primitive position.
