ABSTRACT:
A tensioning member for achieving and maintaining a desired tension in a flexible strap, web or belt is provided. The tensioning member includes an elongate tensioning member having a pair of cam-like cross-members around which the strap is threaded. The elongate member is rotatable through substantially 180.degree. of arc from a release position to a tensioned position. In the tensioned position, the path of the strap through the tensioning member is longer than when the tensioning member is in the release position. This causes the tension in the strap to increase as the tensioning member is rotated from a release position to the tensioned position. One end of the tensioning member is extended to provide a mechanical advantage for rotating the member to the tensioned position. A keeper or retainer encircling the strap and movable therealong engages the extended end of the tensioning member to secure the tensioning member in the tensioned position. Preferably, the tensioning member has a dog-leg shape to hold the tensioned strap away from an underlying surface when the tensioning member is in the tensioned position.
