<p>The device has a lower channel part with 2 side walls joined by a floor, at least one angled insertion lug near each edge and an upper part joined to the lower part with 2 lateral wall regions joined by a base, each in contact with a lower part side wall and designed to latch to it. At least one insertion lug stop element is formed on the base of the upper part so the lug is clamped between upper part lateral wall regions and stop element(s). The device has a lower channel part (11) that is essentially of U-shape and has two side walls (13,14) joined together via a floor (19) and with at least one angled insertion lug near each edge and an upper part (12) joined to the lower part with two lateral wall regions (20,21) joined by a base (22), each in contact with a side wall of the lower part and designed to latch to the lower part. At least one stop element for an insertion lug is formed on the base of the upper part so the lug is clamped between the lateral wall regions of the upper part and the stop element(s).</p> |
