<p>The elastically deformable pin surrounds the wire, completely preventing contact between the wire and the posts which would lead to chafing and deterioration of the wire. The pin (15) has a circular head (16) of internal diameter equal to the diameter of the wire, and two tapered arms (17), the rear of the arms being notched (18). The post (12) has a curved rebate (13) with a drill hole (14) in the base large enough for the pin to enter when the arms are pressed together, the edges of the hole engaging the notches in the pin.</p> |
