Improved keyring, essentially characterized in that it is constituted by a rigid body, predominantly annular irregular, having an area of its open periphery, at opposite ends of which there are blind holes for receiving the coupling of a telescopic piece closing said opening, the two parts that form the telescopic piece, to adopt a position of maximum extension, depending on the force of an expansion spring that carries inside.
