Abstract
Arrangement in a sewing machine shuttle for holding in place a hook ring (10) in a driver (19) consisting of three parts: an inner part (23), an intermediate part of spring material (24) and an outer part (25). The elastic intermediate part keeps the hook ring in a determined position but allows, at the same time, the passage of the upper thread without any considerable obstacle.
