<p>A fastening clip, especially for securing a plate having a coil to release a burglar alarm, to an article of clothing, comprises a housing (1) having opposed side walls (5, 6) converging towards an opening (2) which is situated close to one (6) of the walls and through which a shank (3) of a pin member (4) is inserted. A roller (7) having a circumferential guide groove (8) is so mounted between said walls (5, 6) that when inserted the shank (3) presses the roller (7) away from the opening (2) against the bias of a pressure spring (9). On a subsequent pull outwards of the shank (3), the roller (7) will be wedged and by friction will prevent the shank (3) from being withdrawn. The wall (6) or a metal plate (10) strengthening said wall is preferably provided with a groove (11) forming a guiding for the shank (3) so that it will not tilt. The fastening clip is more simple and cheaper to produce than corresponding fastening clips wherein two or three balls are used, which are mounted in radial channels of a special spring-biased guiding body. </p> |
