What is the name of the long cable/plug attachment on the MacBook MagSafe charger? My MacBook 2015's MagSafe charger has two attachments for plugging it into the wall:


a simple plug, which slides/snaps onto the charging block
a loooong cable, one end of which can slide into the charging block and the other end has a plug on it for going into the wall


I would like to know the name of the second attachment.
The cable in question (pun intended) is called Power Adapter Extension Cable.


  Overview
  
  The 1.8-meter Power Adapter Extension Cable is an AC extension cord that provides extra length for your Apple power adapter. Use it with MagSafe and MagSafe 2 power adapters, 10W and 12W USB-A power adapters, and 29W, 30W, 61W, and 96W USB-C power adapters.
