The base includes a projection extending outwardly from the base. An opening is disposed in the projection. The cover includes a locking member configured to be received by the opening in the projection when the cover is connected to the base. The cover is configured to rotate about a pivot axis of the locking member to disengage the locking member from the opening in the projection to remove the cover from the base. ## Claims ### Claim 1 A locking assembly for a fuse box of a vehicle comprising: a base, the base including a projection extending outwardly from a wall of the base, an opening being disposed in the projection, the opening being defined by a tab of the projection and the wall of the base, the projection being resiliently connected to the base; and a cover configured to be removably connected to the base, the cover including a locking member configured to be received by the opening in the projection when the cover is connected to the base, the cover being configured to rotate about a pivot axis passing through the locking member to disengage the locking member from the opening in the projection to remove the cover from the base, the pivot axis being spaced from and extending between the wall of the base and the tab of the projection when the cover is connected to the base when viewed in a direction parallel to the pivot axis. ### Claim 2 (depends on 1) The locking assembly according to claim 1, wherein the cover is rotated approximately thirty-two degrees to disengage the locking member from the projection opening. ### Claim 3 (depends on 1) The locking assembly according to claim 1, wherein the locking member includes first and second tabs extending outwardly from the cover. ### Claim 4 (depends on 3) The locking assembly according to claim 3, wherein the locking member includes a post extending between the first and second tabs, the pivot axis passing through the post. ### Claim 5 (depends on 4) The locking assembly according to claim 4, wherein the locking member includes a hook extending from the post, the hook engaging the projection when the cover is connected to the base. ### Claim 6 (depends on 5) The locking assembly according to claim 5, wherein the hook is rigidly connected to the post. ### Claim 7 (depends on 4) The locking assembly according to claim 4, wherein a protrusion protrudes inwardly from the projection toward the base to define a gap between the protrusion and an outer surface of the base. ### Claim 8 (depends on 7) The locking assembly according to claim 7, wherein a length of the gap is smaller than a width of the post. ### Claim 9 (depends on 1) The locking assembly according to claim 1, wherein the locking member is unitarily formed with the cover as a single member. ### Claim 10 A fuse box assembly for a vehicle comprising: a fuse box base; a fuse box cover movably connected to the fuse box base between a first position and a second position, the fuse box cover being connected to the fuse box base in the first position and removable from the fuse box base in the second position; a projection extending outwardly from a wall of the fuse box base, an opening being disposed in the projection, the opening being defined by a tab of the projection and the wall of the base, a protrusion protruding inwardly from the projection toward the fuse box base to define a gap between the protrusion and an outer surface of the fuse box base; and a locking member received by the opening in the projection when the fuse box cover is in the first position and the locking member being removable from the opening in the projection when the fuse box cover is in the second position, the fuse box cover being configured to rotate about a pivot axis passing through the locking member to move between the first and second positions, the pivot axis being spaced from and extending between the wall of the base and the tab of the projection when the cover is connected to the base when viewed in a direction parallel to the pivot axis. ### Claim 11 (depends on 10) The fuse box assembly according to claim 10, wherein a plurality of locking tabs extending from the fuse box cover are configured to be received by a plurality of openings disposed in the fuse box base, each locking tab being received by a different opening to further secure the fuse box cover to the fuse box base. ### Claim 12 (depends on 11) The fuse box assembly according to claim 11, wherein each of the fuse box locking tabs is disengaged from the corresponding fuse box base opening prior to rotating the fuse box cover from the first position to the second position. ### Claim 13 (depends on 10) The fuse box assembly according to claim 10, wherein the fuse box cover is rotated approximately thirty-two degrees between the first and second positions. ### Claim 14 (depends on 10) The fuse box assembly according to claim 10, wherein the locking member includes a post extending between first and second tabs extending outwardly from the fuse box cover, the pivot axis passing through the post. ### Claim 15 (depends on 14) The fuse box assembly according to claim 14, wherein the locking member includes a hook extending from the post, the hook engaging the projection when the cover is connected to the base. ### Claim 16 (depends on 15) The fuse box assembly according to claim 15, wherein the hook is rigidly connected to the post. ### Claim 17 (depends on 10) The fuse box assembly according to claim 10, wherein a length of the gap is smaller than a width of the post. ### Claim 18 (depends on 10) The fuse box assembly according to claim 10, wherein the locking member is unitarily formed with the fuse box cover as a single member. ### Claim 19 A locking assembly for a fuse box of a vehicle comprising: a base, the base including a projection extending outwardly from a wall of the base, an opening being disposed in the projection, the opening being defined by a tab of the projection and the wall of the base; and a cover configured to be removably connected to the base, the cover including a locking member configured to be received by the opening in the projection when the cover is connected to the base, the cover being configured to rotate about a pivot axis passing through the locking member to disengage the locking member from the opening in the projection to remove the cover from the base, the pivot axis being spaced from and extending between the wall of the base and the tab of the projection when the cover is connected to the base when viewed in a direction parallel to the pivot axis, the locking member including first and second tabs extending outwardly from the cover and a post extending between the first and second tabs, the pivot axis passing through the post, and the locking member including a hook extending from the post, the hook engaging the projection when the cover is connected to the base.
