Abstract
A cable tie is moulded in one piece and comprises an elongate flexible strap provided with ratchet serrations on one side and a head at one end of the strap, the head having an aperture provided with a pivoted pawl having teeth which engage the ratchet serrations of the strap when the free end of the strap is passed through the aperture. The pawl teeth have their crests in a common plane, in the moulded condition of the tie, which lies substantially perpendicular to the plane of the strap. The aperture is formed opposite the pawl with an abutment surface which is inclined to the common plane of the pawl teeth so that the pawl tooth furthest from the pawl pivot is closest to the abutment surface.
