A cross-connection (1) made of sheet metal is used to connect C-profile bars (2, 3) of under-decks, situated at the same height and crossing at right angle. The cross-connection (1) comprises a flat connection plate (4), configured like a cross, from which start four flat arms (5). Ratchet tongues (7) which are angle formed on the side of the flat arms (5) present each a ratchet part (8) projecting outwardly and a point skewed inwardly. A splice piece (10) projects horizontally from each side edge (6) of the side arms (5), next to a ratchet tongue (7). |
