A device for the manual attachment of buttons and the like onto fabric or other supports includes two needles (1'), a stretchable ring (11) and a counterbutton (4) with a hole (6) and two pairs of fastening sites (7), each needle (1') having a point (2) at one end and means (8, 9) for releasably engaging the stretchable ring (11) at the other end.
A corresponding attachment method which makes use of said device includes the following steps:

a) threading the needles (1') through the holes of the button;
b) piercing the fabric from the outside until the needles (1') come out on the other side so as to have corresponding loops of the stretchable ring (11) projecting therefrom;
c) threading the needles (1') through the hole (6) of the counterbutton (4);
d) stretching a loop of the stretchable ring (11) by pulling the relevant needle (1') until the end (7a) of a fastening site (7) is introduced into said loop and then pulling the loop towards the other fastening site (7) until the other end (7a) is introduced therein;
e) repeating the preceding step for the other loop of the stretchable ring (11);
f) disengaging the needles (1') from the stretchable ring (11).
