The icon is a picture of handcuffs. The icon is shaped like two circles attached to a 2 link chain. Each circular object has a key hole looking structure between the hole in the circle and the point it attaches to the links
This is a Handcuffs icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,300 icons, all in the same style and quality.
