A safety collar for a vault box reduces the risk of catastrophic injury if the pole vaulter lands directly onto the vault box, but does not make it more difficult for the pole vaulter to plant the pole into the vault box. The safety collar overlies the vault box and an area to the rear and the sides of the vault box. The collar has a front, a rear, a left side, a right side, and an opening extending from the front to the rear that overlies the recess of the vault box. The collar also has a left wing extending downwardly against the left wall of the vault box part way to the bottom surface and part way to the rear wall and a right wing extending downwardly against the right wall of the vault box part way to the bottom surface and part way to the rear wall.
