ABSTRACT:
To improve a strap clamping device comprising a clamping strap forming an outer loop to wrap around one or several workpieces, and a tightening device for tightening the outer loop to clamp the workpiece or workpieces, such that it is operable in as convenient a way as possible, it is proposed that the tightening device comprise a base element supported on the loop with a guide opening through which the loop is guided, that the tightening device include a pull element, that the pull element and the base element be moveable relative to each other by means of an adjusting device, and that the loop run between the base element and the pull element and engage the pull element such that upon relative movement of the base element and the pull element, the outer loop is tightenable under the effect of a double pulley.
