An eccentric tensioning device for tensioning the traction means of a traction means drive is provided. The invention provides solutions, through which advantages are given in the installation of tensioning devices under assembly-specific aspects. The eccentric tensioning device for a traction means drive includes a track roller device, which has a running disk and a rolling bearing provided for supporting this disk, a work eccentric for supporting the track roller device such that it can be displaced in a radial direction relative to the rotating axis of the rolling bearing through pivoting of the work eccentric, a torsion spring for pretensioning the work eccentric, and a fixing device for securing the work eccentric in a mounting position, in which the torsion spring is located in pretensioned state. The fixing device is constructed such that it can be brought into a released state during attachment of the eccentric tensioning device to a flange surface, in which the running disk is forced radially relative to the rotating axis of the rolling bearing against the associated traction means due to the work eccentric. Therefore, it is possible in an advantageous way to create a tensioning device, in which during the mounting of the traction means, the work or the operating eccentric is fixed in an end position and an activation of the tensioning device is guaranteed in a reliable way.
