Mamiya RZ67 No.1 Slip on Hood

I've recently required the use of the Mamiya RZ67 No.1 Slip on hood for some landscape work with a 65mm lens. I bought one and in addition to it slipping on it also slips off quite easily. So after slipping it on I added UV filter to hold it in place. Is this a correct way to do this or is there another trick to holding this particular hood in place? I'd appreciate any suggestions.

Thanks,

Charles
