Abstract: The object of the invention finds application in the field of clothing, and more precisely in the shirts with the neck ready to use of the tie. Very often the shirt is worn without a tie and with open neck. The aesthetic result is decidedly inelegant. The idea is to solve the need for freedom of movement of the neck and at the same time to maintain a formal elegance. The invention addresses this need with an accessory, applicable to normal shirts, using the slot and the little button in the neck. The accessory is a visible link with significant aesthetic value. The accessory is made from a button (1), a lanyard shot to double back on it-self (twisted pair) (2), two sliders (3). The pair, to length, is the flexible element that brings together the button and two sliders, hooks up to the shirt stud (5) and acts as a spacer between the stud and the slot of the neck. The sliders run on twisted and tighten the accessory to the stud (5) and to the slot (4) of the neck.
