The invention relates to a tensioning/relaxing element that comprises a base ( 3 ), at least one rotating shaft ( 4 ) mounted on said base, a mobile part ( 2 ) and a lashing device ( 1 ). Between said base ( 3 ) and the at least one shaft ( 4 ) at least one nonpositive and positive element ( 5, 6 )

The invention relates to a tensioning/relaxing element that comprises a base ( 3 ), at least one rotating shaft ( 4 ) mounted on said base, a mobile part ( 2 ) and a lashing device ( 1 ). Between said base ( 3 ) and the at least one shaft ( 4 ) at least one nonpositive and positive element ( 5, 6 ) is provided that tightly encloses the shaft ( 4 ). The first nonpositive and positive element ( 5 ), configured as a tensioning element, is firmly linked on the one side ( 5 a ) with a part ( 2 ) that is mobile vis-a-vis the base ( 3 ) and can be actuated on the other side ( 5 b ), with a variable and continuous pretension, via a first actuator ( 11 ), while the second nonpositive and positive element ( 6 ), configured as a relaxing element, is firmly linked on the one side ( 6 a ) with the base ( 3 ) and can be actuated on the other side ( 6 b ), with a variable and continuous pretension, via a second actuator ( 11 ′). The invention is characterized in that the tension force or relaxing force can be continuously modified during the tensioning or relaxing process.
