A tie bar is a structural element used in construction and engineering to connect two or more components, providing stability and support. It is commonly made of metal and is designed to resist tension, helping to maintain the alignment of structures like bridges and buildings. In the context of clothing, a tie bar is a small accessory that holds a necktie in place, preventing it from swinging or moving around. Typically made of metal, it clips onto the tie and the shirt, adding a touch of style while ensuring the tie remains neatly positioned throughout the day.
