Connect/Plug icon
**Description**
The icon should indicate the state of being _"connected/plugged to"_ in various meanings, it also may be used as a metaphor for the action _"to connect/plug"_. For instance, indicate that _"connection to database/server has been established"._

Of course, the icon should be designed in pair with the opposite state _"disconnected"_ and action _"to disconnect from"_. 

**Screenshots**
This is a good example of how it might look like:

**Additional context**
Since the idea of being _"connected/disconnected"_ is basic for web development, I hope it will be designed and added to icon set very soon.
Thanks in advance!
