Tube, a.k.a. staff, connectors have integrated snap buttons that securely connect any two flow tubes.
The connectors are made of polycarbonate, the strongest clear plastic available, and have built-in suspension that cushions flowlights for high impacts.
The buttons are slightly sloped in one direction, so twisting a tube one way releases one half of the connector, while twisting the other way releases the other half - very convenient when you are transforming your props.
Plus the staff connectors' highly-engineered structural design looks really cool!
