ABSTRACT OF THE DISCLOSURE A self locking fastener is described. The fastener is generally C-shaped in transverse cross-section and is radially compressed when fitted with an opening in use. Outwardly projecting barbs on the fastener mechanically engage the inner wall of the opening. Movement tending to remove the fastener imposes mechanical shear forces on the barbs,which forces tend to resist removal of the fastener. In one aspect of the invention the fastener is fitted to a screw body to form a self-locking set screw. In another aspect, the fastener is in the form of a spring pin.
