Pocket clip for writing instruments

A pocket clip for a writing instrument, such as a ball-point pen, fountain pen cap, or the like, comprising:

• a clasp of spring-elastic strip material having a resilient tongue with a free end;
• an elongated facing disposed on said tongue, and stamped from thin metal material, said facing having a substantially planar elongated web and two low marginal flanges respectively formed on lateral margins of said web and extending away therefrom;
• at least one holding bead extending from each of said marginal flanges over a portion of the length of the respective marginal flange and bent toward the other holding bead;
• there being a free space between the web and the beads, said free space being approximately equal to or only slightly greater than the thickness of the resilient tongue and the width of the facing being slightly less than the free width between the marginal flanges, so that the free end of the tongue is insertable into the space between the web and the flanges;
• the facing having an upper end to be fastened to the writing instrument, and two tabs at said upper end, formed on the flanges and having free ends bent to a position in which they point toward one another, said tabs having bottom transverse edges and being so disposed that in a fastening position of the clip the resilient tongue in locked against withdrawal from said facing by said edges;
• the width of the beads being such that a narrow, slot-like interstice remains therebetween, the tongue having at least one first projection which, in the fastening position, protrudes above and directly behind the bead opposite the end of insertion of the tongue, said first projection having a diameter greater than the width of the slot-like interstice.
