Abstract
The invention concerns a hold-down fastener including a barrel including internal lips cooperating with a screw thread, the lips being directed inwards of the barrel and inclined in a direction of insertion of the screw into the barrel. Each lip includes at least two parts, a first part connected to the barrel and inclined at a first angle relative to the barrel, on the side for inserting the screw, and a second part connected to the first part and inclined at a second angle relative to the barrel, on the side for inserting the screw. The second angle is larger than the first angle and less than 180° to facilitate the insertion of the screw into the barrel, while maintaining the fastener screw-holding power after the screw has been inserted. The invention is useful for fixing in place electric cables, piping systems, and other cylindrical articles.
