ABSTRACT:
A tension connection for a building includes a first tension member, the first tension member being anchored at its distal end, a second tension member being anchored at its distal end; the first and second tension members being disposed in close proximity and connected by a coupler having a surrounding sleeve and a central bore with a thread, the coupler also being formed with a first rotational member being received in the central bore of the surrounding sleeve and operatively connected to the surrounding sleeve; the first rotational member is connected to the surrounding sleeve, such that the rotational member can rotate in relation to the surrounding sleeve. A torsion spring connects the first rotational member and the surrounding sleeve; the torsion spring biasing the first rotational member and the surrounding sleeve in opposite rotational directions such that the first rotational member can be drawn into the surrounding sleeve.
