• wherein for fixing to the support profile, the securing element is twistable relative to the support profile between:
• a first position in which the engagement element remains separate from the support profile so that the securing element is movable transversely on the holding side relative to the support profile;
• and
• a second position in which the engagement element engages on the support profile so as to fix the securing element to the support profile, and in which the closing profile is fixable to the securing element;
• and
• in the second position, the securing element is designed to secure the wall elements, and the closing profile includes a blocking element in order, on fixing of the closing profile to the securing element, to prevent the securing element from twisting back from the second position to the first position.
