Abstract: A fencing section comprises a rod panel which is attached in the edge zone on both sides to an adjacent post in a number of attachment points by using of an attachment device. Such a device has a frontal part and a side part containing a horizontal groove wherein a horizontally extending section of the mesh panel runs. For a first part number the groove is located in the upper surface of the device, and for the other part number in the lower surface of the device. The device has a stud in its frontal part that fits into an opening in a frontal vane of the post. In at least one of the two part numbers, the device is elastically deformable. Such a fencing section is easy to assemble, but is extremely difficult to dismantle by vandalism.
