An anchor for spinal electrical stimulation leads having a first, extended portion adapted to be inserted through the spine and into the spinal column, and a second, shorter portion adapted to be sutured to the fascia on the outside of the spine. The extended portion assists with positioning of the electrode tip onto the spinal cord on provides strain relief for the electrode. The anchor further comprises an inner tube disposed inside of the housing along an intermediate portion between the extended portion and the shorted portion. When the outside portion of the tubular housing is sutured to the fascia of a patient, the inner tube is compressed against the electrical lead, thereby locking it in place and preventing migration over time.
