Looks like there should be some thing on the bar - if you zoom in on exploded parts diagram there is something there but it's not at all clear. Something like a bolt shank ? 

Are you still using the original bar? 

Other than that, I guess you wind back the spring lever widget thingee while fitting the side cover over the bar studs then release the spring to push against the feature in the bar .....

 

All a bit of a punt,  not seen one like this before.

This is the tooless adjustment , as others have said there should be a ratchet plate on the guide bar that appears to be missing on the new bar, I have never seen this part as spare. I can sort a part number out if you wish for the correct bar.

From McCulloch website   

 

BRO073 - Chainsaw Bar 3/8" Pitch - Chain Tensioner

 

There is a pin fitted to the bar in top hole which the tensioning lever engages by the look of it. Part No BR0073

 

Ebay bar doesn't have this

If you haven't got a manual you can get one from McCulloch site which shows how to tension the chain.
