Abstract: A tunnel connector for an in-ground storm shelter which allows inhabitants to enter the in-ground storm shelter from a trailer house without being exposed to external environmental factors. The tunnel connector includes a U-shaped enclosure wall, a staircase, a first lateral wall, and a second lateral wall. The first lateral wall and the second lateral wall are connected perpendicular to the staircase across each other to provide lateral protection. The U-shaped enclosure wall includes a first sidewall, a second sidewall, and an interconnecting sidewall. The interconnecting sidewall is terminally connected in between the first sidewall and the second sidewall. The first lateral wall is adjacently connected to the first sidewall, opposite the interconnecting sidewall. Similarly, the second lateral wall is adjacently connected to the second sidewall, opposite the interconnecting sidewall. The tunnel connector is installed in between a floorboard of the trailer house and the in-ground storm shelter.
