Abstract: A tensioner for the controlled clamping and forward movement of an elongate element, in particular for winding/unwinding a cable, a hose, a pipeline or an umbilical on a reception member. The tensioner comprises at least one frame that carries three guide boxes arranged around a passage axis. This tensioner comprises means for maneuvering these guide boxes, in particular second maneuvering means for the maneuvering in rectilinear, or at least substantially rectilinear, translation of lateral guide boxes, respectively in a direction defining an angle of between 115° and 125°, and preferably between 118° and 122°, with respect to said central plane. These second maneuvering means comprise at least one rocker element comprising a proximal end mounted so as to pivot on said frame and a distal end mounted so as to pivot on said lateral guide box, respectively about rotation axes extending parallel to said passage axis.
