Arduino and JR plugs

Hello!

I plan to buy some servos from HobbyKing : http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=16265
As you can see in the description, the plug is a JR one.
I have a Arduino Uno: are these JR plugs compatible with the Arduino? If not, is there any way to make them compatible?

Thanks in advance for your help. :slight_smile:
