@SFK It's not that one. It's the Logitech Driving Force Feedback E-UC2 made exclusively for the PS2 I think, which really should be in a museum (must be about 20 years old), or does your lad have a PS2?
Anyway, that aside I think there should be two clamps that fit into the two slots in the bottom which allow it to be clamped to the edge of a table and then they are tightened with those two knobs on the top (just beneath the wheel), assuming you don't have them, I'm guessing that yours was sold missing the clamps, the chumps in CEX probably have no idea it should have the clamps so I would take it back. Fixing a steering wheel down is essential, it won't work if it's not fixed down, well it would work but it'd just be absolutely awfully frustrating to use.
