end the fingers 46 cooperating with the notches 36 in the manipulating member 32 so as to permit selective adjustment therealong the fastening device is fabricated and assembled in the following manner the manipulating member 32 is fabricated from a thermoplastic material through an injection molding process as shown in fig2 and 3 the retaining flanges 37 are molded such that they extend transversely from the body of the manipulating member 32 adjacent the notches 36 also the two spaced apart members 48 extend outwardly from the manipulating member 32 in attaching the wire member 12 to the manipulating member 32 the trunnion portion 18 of the wire member 12 is placed within the concave recess defined between the pair of spaced apart members 48 of the journal member 30 as best seen in fig5 the spaced apart members are then ultrasonically deformed such that they are folded toward each other over the trunnion portion 18 of the wire member 12 as best seen in fig4 and 5 the retaining flanges 37 are also deformed such that they no longer extend transversely from the manipulating member 32 but rather extend inwardly parallel to the manipulating member 32 across the top of the notches 36 the interconnecting wire member 42 is now attached by guiding the wire portions 14 and 16 of the wire member 12 within the loop portion 44.
