A lead anchor includes a core housing defining a cavity a swivel anchor disposed in the cavity and having a tubular portion and a locking portion at least two locking members and at least two sleeves with a portion of each of the sleeves and each of the locking members disposed within the cavity at a periphery of the cavity. The tubular portion is adapted to receive an external tool to rotate the swivel anchor within the cavity. The lead anchor has an unlocked configuration, in which the swivel anchor can rotate within the cavity of the core housing without compressing the sleeves, and a locked configuration, in which opposing ends of the locking portion of the swivel anchor each lie between one of the sleeves and one of the locking members and compress the sleeves and any lead disposed within the sleeves to hold that lead in place.
