摘要

The device has a snap-on fixing element (5) with a trapezoidal sheet plate portion (6) including curved oblique edges, and slot (10) is provided at proximity of base of the edges. The portion is connected to a snap-on fixing element (14) by tongues (20, 21) that extends one of bases from the portion and have reduced width folding zone so that a folding resistance is less than a folding resistance of the portion. The snap-on fixing elements are connected to each other by a connection (18) formed by a web extension (15).
