Abstract: An elongated strip, for holding fastening elements (5) for use in explosive powder charge operated setting tools, forms a plurality of consecutively arranged hollow, cylindrically shaped spaces for holding the fastening elements (5) and with the spaces interconnected by flexible webs (2, 3). The spaces (1) each have a central axes and are positioned between parallel sidewalls extending in the elongated direction and arranged parallel to the central axes. First flexible webs (2) are formed in the sidewalls between adjacent spaces (1). The height (H2) of the first webs (2) measured parallel to the central axes of the spaces (1) are in the range of 0.3 to 0.6 times the height (H1) of the sidewalls (4) measured parallel to the central axes of the spaces (1).
