There can be a smell around the tank valves without any leak. Especially on old tanks.
Propane itself is odorless, what you smell is an additive, it's there for your safety. With time, rubber absorbs this smell. Also, additive will mix up with residual oils that are always present in propane, and the smell will cling to valves and orifices.
Like others noted, rubber hose before the regulator will often develop tiny cracks and leaks - in addition to absorbing the smell, so you can have smell with and without leaks.
