A corner key ( 10 ) for connecting profiles ( 12, 14 ) together and a frame work assembly formed of such corner keys ( 10 ) and (profiles ( 12, 14 ). Each profile ( 12, 14 ) has an anchoring channel ( 16, 18 ), a drainage and venting passage ( 20, 22 ) and a securing bore ( 24, 26 ). The corner key ( 10 ) has two adjacent inner corner faces ( 28, 30 ), two adjacent outer corner faces ( 32, 34 ), and opposite inner and outer side corner faces ( 36, 38 ). Tabs ( 40, 42 ) on the inner corner faces ( 28, 30 ) guide the coupling of the profiles ( 12, 14 ). Fasteners ( 48, 50 ) are inserted through the outer corner faces ( 32, 34 ) in corner key bores ( 44, 46 ) and in the bores ( 24, 26 ) of the profiles ( 12, 14 ). A drainage and venting passage ( 52 ) in the corner key ( 10 ) communicates with the drainage and venting passages ( 20, 22 ) of the profiles ( 12, 14 ).
