饰绳是军服用吊在单肩上的装饰用结绳。

一种说法是，最早是法国骑兵将军身边的扎营侍卫，平时挂在肩上的牵马用绳具。

另一种说法是，本来是参谋或是副官为了方便携带在地图上画记号的笔记用品所用的绳具。到了现代，绳索先端吊笔的部分已经演变成为挂着一种称作「铅笔」（英语：pencil）的金属头作装饰。

An aiguillette (from French "aiguillette", small needle) is an ornamental braided cord most often worn on uniforms, but may also be observed on other costumes such as academic dress, where it will denote an honour. Originally, the word "aiguillette" referred to the lacing used to fasten plate armor together. As such, a knot or loop arrangement was used which sometimes hung from the shoulder.
