Retaining element for building sheets

Abstract

Disclosed is an elongate retaining element for building sheets, having in plane perpendicular to its direction of elongation, a head part which is substantially triangular in cross section. The head part including one or more movable rotationally symmetrical elements. The movable rotationally symmetrical elements are positioned at one or more vertices of the triangle. The head part includes one or more mountings in which the elements for engaging the building sheet are mounted. The mountings are attached to the head part by fixing elements.
