Mine broke off 1 side about a month before the other side broke of. I still run mine on the bracket, just so that the part of the clip supports the pump. On the ones that are completely broken, I epoxied the lead to the edge of the tank to hold it in place to help it be supported, untill the new brackets turn up.
Can't wait for the new brackets though, it will be good to control the flow.
Cheers
