Abstract of the Disclosure A tension device which comprises a housing having a yarn passageway extending therethrough, which passageway has a large diameter section and a small diameter section. An outer end of the large diameter section of the passageway is provided with rounded abrasion resistant corners. An uninterrupted seat is provided along the passageway at the junction of the large and small diameter sections and has an opening therethrough. The seat receives a spherical element thereat and holds the spherical element out of contact with walls of the large diameter section of the passageway when no yarn is passing through the opening. The seat has surfaces around the opening with a radius of curva- ture opposite the curvature of the spherical element. A spheri- cal element is received in the large diameter section of the passageway. A spherical element has a diameter which is less than the length of the large diameter section. The large diameter sec- tion has a diameter adjacent the seat to prohibit substantial lat- eral movement of the spherical element received thereat.
