  • Such a tension screw has a tension screw body that has a spindle passage for a screw spindle at one end. At the other end, the tension screw body is designed and constructed to interact with a free end of a lashing rod and its thickenings/knobs in a hookable manner. A locking piece is inserted into the free end of the threaded spindle, which points towards the holding piece of the tension screw body for the lashing rod, with which an unintentional rotation of the screw spindle relative to the tension screw body can be blocked.
  • clamping screws have proven themselves. However, it is desirable to realize an increased range of possible clamping lengths L between a minimum clamping length Lmin and a maximum clamping length Lmax, particularly in the case of geometrically unchanged or predetermined clamping screw bodies.

It is thus possible to increase the adjustment range of the tension screw for a certain tension screw body length by the possibility of the free ends of the tension elements dipping into one another. With the invention, it is therefore possible to cover an increased tension length range in a particularly simple manner, although only a tension screw according to the invention of a certain size has to be combined with a lashing rod of a predetermined length.
