Abstract:
Tightening device of the screw-nut type includes a tightening member, which can be rotated, and a rotary wrench for this tightening member, equipped with a handling arm. The wrench and the tightening member are joined by a connecting device in such a way that the wrench can swivel in relation to the tightening member around a swivel axis substantially perpendicular to the screwing axis of the tightening member. Thus, it can be placed in a rest position substantially perpendicular to the screwing axis and can rotate the tightening member around the screwing axis or rotated freely in relation to the tightening member around the screwing axis, over a range of angular clearance (α) of at least 170°.
