<p>The fastener has a band (10) having a series of notches (11) held by a tongue (22) protruding inside a passage (24) in an anchoring head (20) located at one end of the band. The band comprises a case (30) enclosing the head (42) of a pin whose spindle (44) passes freely through the wall of the case bottom (32), and whose end is fixed to a plate (46). The case side walls (34) are open. The fastener is made by thermoplastic injection in a mould in which the perimeter of the pin spindle is formed by a double series of circular arc shells. The first series (100) pass through the pin head and the bottom wall of the case. The second series (200) pass through the plate and the wall of the case bottom parallel to the spindle. <IMAGE></p> |
