Les,
It appears that what you got was the Legend II hose body with the metal swivel (no bleeder holes) and the hose locking nut for the separate suction and blower couplers (models 505 to 562). You will need to find the metal suction coupler (part #2100 for models 505-515; #210056 for models 516-562).
The Sanitronic VII was the first Kirby to have the hose with a permanently-attached universal suction/blower coupling. That also meant a slightly-redesigned O-ring on the fan case to support it.
The separate blower coupler that attached to the neck (blower) end of the motor unit was also made of metal... until the 519, which changed to a red plastic version (tan plastic for model 562). That was part #2120 for models 505-515, #212056 for models 516-518, #212059 (red plastic) for models 519-561, and #212062 (tan plastic) for model 562.
The metal suction and blower couplers for models 505-515 will not work with models 516-562, as the fan case on the latter group of machines has an O-ring on their fan cases to ensure better suction, while the metal blower coupler for models 505-515 only have two attaching slots instead of three.
The proper Legend II hose, with the fittings specific to said model (all plastic), was part number 223688/223692.
