<p>The plastic press stud is in two parts; one part (10) with a sphere is attached to a holder; and the second part has a sprung eyelet with two radial flanges (11, 12) for fixing onto a flat cover with hole in. The radial flanges (11, 12) of the first section (10) protrude axially, with the bottom flange having a radial cavity (15) extending beyond its circumference. The bottom flange (12) is joined to the top flange (11) by means of at least one curved bridge piece (18, 19). The inside of the bridge piece has an undercut part. The outside of the top flange (11) has an outward pointing operating protuberance (23).</p> |
