Is there a master link for single speed chain that will fit in Shimano chain tensioner? I've got a bike with planetary hub Shimano Alfine 8-speed and this chain tensioner. It uses single speed chain. However master link on the chain I bought (similar to this pic) is too wide to fit in the chain tensioner. Is there another master link that will fit? Where do I buy it?

Edit: I made a mistake when I purchased chain with 1/8 inch width, my cog and everything else are made to work with 3/32 inch chains.
Assuming you have a new KMC chain (pic of the connector is KMC).

KMC definitely makes 1/8" chain connectors of the 'Missing Link' style without the extra side plate clip that is presumably causing problems.

Can't tell you if those are readily available in Russia or where the best place to buy them is.
