Improved keyring essentially characterized by consisting of a piece of rigid filar structure defining an open loop of non-coplanar terminations and provided with a thread, conjugated with that made in the mouthpieces, terminals in the converging areas of two pieces of general shape of body of revolution, advantageously, in its areas of greater diameter, faceted elements and in their lateral surfaces longitudinal notches cooperating to the immobilization of the assembly by effect of friction resulting between the two parts in contact after their threading at the terminations of the first element.
