I can't see enough detail on your cylinder but generally it is released by moving a spring loaded retainer which is captured in a groove in the lock housing.

On the one I posted it is the large brass piece at the left of cylinder just before end. The regular key locking pieces are the 5 tabs 90 degrees from it at the top. My lock releases by placing the cylinder in a certain position and pushing against the clip from the side.

Without seeing your cylinder, I suspect it works very similar except that with the hole where it is, the paper clip will be pushed down into the housing past retainer and in a position so when the cylinder is turned, it will meet the paperclip which will act like a ramp and retainer will be forced back against the spring into cylinder and released from the groove.

If you don't have a cylinder that looks similar to the one I posted, then will need more detail to figure it out.

EDIT: If it does work as I suspect, the size of the paper clip may be important as well. Too thin and the retainer may not push back far enough to clear groove.
