This icon is meant to represent a link of chain. It is composed of three links that are represented by intersecting spherical shapes connected by a straight line. It looks just like three links of chain that interlock together.
This is a Link Filled 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 13,100 icons, all in the same style and quality.
