Abstract: A safety bead chain for blinds is revealed. An external member and a mounting member are disposed on two ends of the bead chain respectively. The external member consists of a groove and at least two first locking parts arranged around the groove. The mounting member is set with at least two second locking parts locked with the first locking parts correspondingly. Thus the external member and the mounting member are locked with each other to form a safety bead fastener bead with the same shape as a bead of the bead chain. The two ends of the bead chain are released from each other once a pulling force is applied to the bead chain to keep children from getting tangled in the bead chain. Moreover, the bead chain is moved around the clutch in a circular manner. Users can operate the bead chain more conveniently.
