The pad may have sideways-extending portions for projecting on opposite sides of a clip-retaining member and it may also have projecting islands, possibly chevron-shaped, on one face or on both faces. The base portion may be one member made of soft material and this may be fixed to a separate member made of harder material which is formed with the side portions and the recess.
