Abstract
Improved bolting device, being of the type that are constituted by a metal tube longitudinally folded and that expands or widened by the action of a fluid under pressure, essentially characterized in that the tube has two longitudinal folds, preferably arranged diametrically, which constitute housings in which longitudinally located rods or rods are positioned, which are connected to the end ferrules welded to the tubes, and because in the lateral perforation of one of the ferrules there is a check valve that prevents the exit outside the expansion fluid of the tube once introduced.
