Abstract
Described are a tensioning device and a stand having a tensioning device of this type. In a stand for clamping rod-shaped units (Christmas trees), a flexible force transfer element (wire rope) (4) is wound on a rotatable tensioning body (5) and thus tightened. The rotatable tensioning body (5) is rotated about its rotation axis (18) by means of a drive wheel (7) which is connected non-rotatably to the tensioning body and whose diameter is several times larger than that of the tensioning body (5). A safety catch (6) prevents the tensioning body (5) from turning backwards automatically into the locking position and allows the tensioning body (5) to turn backwards into the release position.
