In a button with a stitchless fastener, the button including a two-part button body having an upper and lower part to be arranged on the front side of a carrier material, the lower part having a top and bottom surface through which two apertures extend and a recess proceeding along said top surface from said apertures, a fastener in the form of a U-shaped staple, the staple having two legs which each have an end thrust through the back side of the carrier material to emerge on the front side, and passed through the two apertures of the lower part and the protruding portions of the ends of the legs and being received in downwardly deformed condition in the recesses and wherein the upper part is connectable to the lower part and covers the recess-containing upper surface of the lower part, the improvement comprising a form-maintaining fastener having two parallel L-shaped legs projecting from a bight, said fastener having and substantially maintaining this preformed shape wherein the ends of the legs serve to hold the button in place without deformation of the shape of the fastener, wherein the lower part has parallel directed recesses corresponding to the parallel legs and originating from the separate apertures, the recesses defining a turning plane for the ends of the legs upon turning motion of the entire staple;
- and an upper part connectable to the lower part and operative to confine the ends of the legs and wherein said lower part further has a wall with an inwardly directed rim surrounding said top surface of said lower part, and confining said upper part.
