The row of spaced apart guide sleeves (2) for the nails (1) has every two sleeves joined by a connecting bridge piece (3) possessing a part (8) radially spaced apart from the lengthwise axis of the guide sleeve by an amount greater than the maximum radial extension of the guide sleeve. The part of the connecting bridge piece has a height (H) parallel with the lengthwise axis of the guide sleeves and less than its width at right angles to the guide sleeves' lengthwise axis and at right angles to the lengthwise extension of the nail-magazine. The guide sleeves between two end parts (E1,E2) have a central area (Z) whose radial measurement is less than that of the two end parts. |
