Air box question
 

Hi
On the bottom section of my air box there are like two female sockets that the bottom end of the lid slot into( then the top end has two clips that fasten it too). I noticed that one of the female sockets has snapped open, so there s nothing for the bottom left side of the lid to slot in to, though it's not overly loose as it's got the right side and the two metal clips at the top.
Do I need to get a new airbox or will it be ok being slightly loose, or will it foooook things up.
If anyone could please advise.
