A side tarpaulin tightener for tensioning a tarpaulin to a mounting structure includes a tension lever-hook module and an adjustment unit. The tension lever-hook module has a tension lever pivotally articulated about a first pivot axis and a hook pivotally articulated about a second pivot axis on the tension lever being spaced apart from and parallel to the first pivot axis. The adjustment unit is pivotally articulated about the first pivot axis on the tension lever and has a base element attached on the tarpaulin and an elongated rod at one end being pivotally coupled to the tension lever at the first pivot axis thereof and at an opposite end being connected to the base element such that a tensioning movement can be transmitted to the tarpaulin as a result of an upward movement of the hook and an opposite downward movement of the adjustment unit relative to the hook in response to an upward closing pivotal movement of the tension lever. Thus, both the tension lever and hook of the tension lever-hook module are pivotably articulated relative to the adjustment unit. The first and second pivot axes of the tension lever and hook are spaced apart from one another such that the distance between them determines the extent through which the hook and adjustment unit can be moved for tensioning the tarpaulin on the mounting structure.
