The plate comprises a U-section holder (2) having a fixing hole in the middle of its web. The holder is formed with transition parts (23) between the web (21) and arms (22) which are symmetrical with the longitudinal centre plane (E) and flatten out the outer corner areas. The inclined transition parts include a substantially normal angle with each other. The arms form in addition to retaining flaps (24) stop tongues (26) extending in an extension of the transition parts. |
