The chain kept coming off of the flush lever inside my toilet tank, so I designed a retainer that keeps the chain from falling off. It secures with 2 zip ties. One zip tie goes through the hole that the chain goes through and the other goes through an unused hole. I am using a pretty generic flush lever so it should fit others as well. My flush lever is 3mm wide and around 10mm tall.
