A device for applying a tensional force between two vertebrae of the human vertebral column, comprising at least two retaining members adapted to be brought into engagement with associated vertebrae, said members having a throughgoing opening for the accommodation of a threaded rod, and pairs of nuts adapted to be threaded onto said threaded rod in order to fix said retaining members in a desired position on said threaded rod, characterized in that said retaining members are configured as clamping members (10) having two legs (14, 16) which are bendable relative to each other in the plane extending through said threaded rod (26) to embrace a transverse process (22) of a vertebra.
