Improvements in the binding means of loose sheets that are characterized in constituting the binder by a band or strip, thermoplastic, flexible and heat-weldable material that is provided, by only one of its lateral edges, a plurality of branches perpendicular to it and distributed regularly throughout its length, which go through two drafts practical two in the area near the edge of each and every one of the loose sheets to bind, so these drafts are practiced distributed with the same regularity as the branches and with a somewhat longer length - than the width of the branch, the length of which is sufficient so that after passing through the drafts to the group of leaves, there is a free part that, once folded, is superimposed on the longitudinal band, to which it is thermowelded said end leaving a loop whose diameter is always greater than the distance that separates the row of drafts from the leaves with its closest edge.
