A plastic nut for multiple detachable fastening onto a stud with a thread protruding from a workpiece includes a base body with an inner surface partially defining a cylindrical recess penetrating the base body. A support surface is attached to the base body at an axial end of the plastic nut. A clamping device is attached to the plastic nut and configured to provide a clamping force between the plastic nut and the stud when the stud is installed in the cylindrical recess.

Plastic nut, fastening system and fastening method

A synthetic material clamp includes a band bent ring-shaped, having band ends with toothed coupling sections together forming a latching coupling. Each coupling section has a first latching element with a latching tooth directed toward a band inner side and a second latching element with a latching tooth directed toward a band outer side. The latching elements are arranged on the coupling sections so the first latching element of a coupling section engages upon closing of the latching coupling. The first and second latching elements are located on opposite sides of a plane centrally dividing the band in a longitudinal direction. The latching elements of both coupling sections include on a side facing the plane a supporting surface arranged when the latching coupling is closed, with the supporting surfaces of one of the latching elements engaging the supporting surfaces of the latching elements of the other coupling section.

Plastic clamp

The invention relates to a fastening device for an elongated object, in particular a cable tree, having a holder () intended for attachment of the elongated object and an adjacency surface () for the elongated object, and having a fastening element () connectable to the holder () for fastening the holder () to a part. For connection of the holder () to the fastening element (), a plug-in assemblable snap coupling is provided, closable by a force directed against the adjacency surface () of the holder ().
