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.
A fixing clamp comprising a barrel which has internally a plurality of lips spaced from one another in the axial direction of the barrel and adapted for cooperating with threads of a screw inserted into the barrel, the lips being directed towards an interior of the barrel and inclined in a direction of introduction of a screw into the barrel, each lip comprising at least two parts, a first part connected to the barrel and inclined at a first angle (α) with respect to a central axis of the barrel, and a second part connected to the first part and inclined at a second angle (β) with respect to the central axis of the barrel, the second angle (β) being larger than the first angle (α) and less than 180°, to facilitate introduction of a screw into the barrel while providing resistance to extraction of the screw after introduction into the barrel, the first angle (α) being between 90° and 135°.
