Methods and apparatus for anchoring an implanted elongate medical device in a body portal, for example, a stimulation lead in a cranial burr hole, employ a securing element attached to an upper surface of a plate member, and moveable relative thereto, from an open position, at which the device may be inserted into a slot of the plate member, and a closed position, at which an engagement surface of the securing element anchors the inserted device. The securing element may extend at angle, with respect to a plane of the plate member, in the open position, and rotating the securing element lifts the engagement surface into the closed position. A locking member preferably extends from an upper surface of the plate member, and, when a latching portion of the securing element moves into engagement with the locking member, the element is moved into the closed position and secured thereat.
