ABSTRACT:
A device for tensioning the corona-discharge wires of e.g. electrostatic copiers has an internally toothed sleeve member in which an externally toothed clamping member is turnably received. Both members have openings transverse to the longitudinal axis of the sleeve member. When an end portion of a corona wire whose other end is fixedly secured, is inserted through both openings in aligned condition of the same, turning of the clamping member draws the end portion between the members, tensioning the wire and clamping the end portion between the teeth of the members.
