A button attaching fastener consisting of a button cap and an attachment plug. The button cap has centrally in its rear surface a socket, and the attachment plug has on one end a flange fitted in the socket with a clench portion provided along an outer periphery of the socket clenched over the flange through its substantially entire surface. The clench portion has on its outer surface a plurality of rotation-preventing projections extending radially outwardly from the base of the flange. The rotation-preventing protections serve to prevent the fastener from rotating on a piece of fabric, as of clothing, and also to increase the pulling strength of the attachment plug.

Dispositif d'attache à boutons constitués d'une partie femelle et d'une partie mâle. La partie femelle comporte centralement dans sa surface arrière une douille, et la partie mâle comporte sur un de ses bouts un collet qui s'ajuste dans la douille avec une partie d'accrochage formée sur la périphérie extérieure de la douille enserrant le collet substantiellement sur toute sa surface. La partie d'accrochage comporte sur sa surface extérieure une pluralité de saillies antirotation s'étendant radialement vers l'extérieur à partir de la base du collet. Les saillies antirotation servent à empêcher le dispositif d'attache de tourner sur une pièce de tissu, par exemple un vêtement, et aussi à augmenter la résistance à l'arrachement de la partie mâle de l'attache.
