An improved needle (1) to attach a filter bag (2) containing a product for infusion to a pick-up tag (3) using a thread (4) knotted at least at one of its end sections (5; 6) comprises two eyes (7, 8) located at different distances from the point (9) of the needle (1). The first eye (7) is designed to hook the thread (4), stretched and retained at the end sections (5, 6) and to make a loop (10) in the thread when the needle (1) is pulled in the direction of its axis (1a). The second eye (8), on the other hand, is located closer to the point (9) and is oriented at right angles to the first eye (7) so that it can be surrounded by the loop (10) and can guide an end section (5; 6) of the thread (4) across the loop (10) to make a knot. The needle (1) also comprises two lengthways grooves (11) that connect the first eye (7) to the second eye (8) and that are especially shaped to accommodate the loop (10) and to keep it in position while the knot is being formed.
