A knotting tongue (44) is supported on the knotting hook (9) with freedom to pivot around a pivot pin (43), which is perpendicular to the plane formed by the knotting hook shaft (40) and the hook part (41) and which passes transversely through cooperating bores (65, 66, 67) in the cheeks (63, 64) and the knotting tongue (44). An internal projection, which extends radially inward in front of the end surface (43′) of the pivot pin (43), is provided In the cooperating bore (66) passing through the cheek (64) of the opening (52). The outer edge of the cooperating bore (65) passing through the other cheek (63) is peened over in front of the end surface (43″) of the pivot pin (43) present there.
