Abstract

Device for fastening a cover plate on a roof, consisting of a hook whose lower end represents a fold to be applied below to the belt of the roof truss a self-retaining washer intended to cooperate with the hook and a body elastomer located between said self-locking washer and the wave ridge of the plate, characterized in that the upper end of the hook is smooth and ends in a frusto-conical part terminated by an axial fin provided with a transverse bore or hole and because the self-locking washer this retention is constituted by an annular body that is provided with a small concentric circular upper recess and in whose central zone it has a circular opening of smaller diameter than the diameter of the shank of the hook, from which a series of incisions or radial grooves originate. As many tabs or elastic-fins in the form of a trapezoid with arched bases, coinciding with the cont of the aforementioned recess, the arrangement being such that when the rod of the hook is introduced into the central opening of the self-retaining washer, introduction that is facilitated by the frustoconical part of the end thereof and by applying it to the hole or bore of its extreme axial fin of an appropriate tool in the form of a hook, the tongues of the retaining washer deform elastically causing a pressure on the surface of the rod that holds firmly together both elements.
