forecast is abolutely right - the idea was to attach the connector to the battery first and then the other connector to the car body elsewhere, so that resulting sparks would be far away from the hydrogen near the battery.
In modern sealed batteries, this is far less of an issue. Attaching directly to the battery terminals is fine - just do one connector at the battery first (keeping the other side carefully separated!). Remove from the non-battery connector first too. FWIW, with all the electronics in cars nowadays, I kinda feel that using the battery terminals directly is better - less current and spikes wandering around elsewhere. I acknowledge that this is a minor point, though.
If you do decide to attach elsewhere, do use someplace where current can flow properly (no paint, solid metal, etc.)
