    Abstract: A wellhead seal assembly that forms a metal-to-metal seal between inner and outer wellhead members. A seal member has inner and outer seal legs separated by a slot. A locking ring is positioned in the outer seal leg and has wickered sections, where each of the wickered sections protrude through a window in the outer seal leg of the seal member. An energizing ring has an upper tapered surface that is oblique to an axis of the annular energizing ring and extending laterally from the axis over a portion of the locking ring and a lower tapered surface that is oblique to and extending laterally from the axis. As the energizing ring is moved into the slot, the upper tapered surface engages an inner surface of the locking ring, and the lower tapered surface engages an inner annular wall of the slot.
