Abstract
A device (1) with a wire holder (13) for securing the upper thread loop (25) after the threading of the upper thread (23) through the eye (5) of a sewing machine needle (3) is provided. The wire holder deflects a progression of the two thread legs of the thread loop (25) upwards and thus securely holds the upper thread (23) in a hook chamfer at the hook (7).
