ABSTRACT:
A button collet for a tufting button comprises a one piece resilient plastic body having a projecting stem that includes a shank and a hook for receiving a tufting loop. The stem has shoulders on its opposite sides in the region of juncture of the shank and the hook. When tension is applied to the loop the forces tending to open the hook are resisted by counter forces applied against the shoulders by the loop, thereby effectively increasing the tensile strength of the collet.
