A tubular lock is a variation of a pin tumbler lock, where the pins are arranged in a circle facing the front of the lock and are operated by a tubular key. It was once referred to as an ACE lock, with ACE being a trademark of the Chicago Lock Company, but the generic term tubular lock is far more common these days.
A variant on the bell is the tubular bell. Several of these metal tubes which are struck manually with hammers, form an instrument named tubular bells or chimes. In the case of wind or aeolian chimes, the tubes are blown against one another by the wind.
