Abstract
A fastening device for preassembling structural members includes a hollow cylindrical body; a bearing ring provided at a proximal end of the hollow body and against which one of the structural members is intended to bear in a fastening position; a pulling threaded rod extending through the hollow body to be inserted into the structural members; a tightening means connected to the pulling threaded rod for maintaining the structural members against each other, the tightening means including a removable tubular end piece for mounting on a proximal threaded end of the pulling threaded rod that can be locally axially compacted under the action of a force applied on the pulling threaded rod in order to form a radial bead for sandwiching the structural members between the latter and the bearing ring; the fastening device including a sheath.
