Abstract: The invention falls within the field of the securing of protective strips covering the ridge or hip regions of a metal roof with standing seams. More specifically, the invention relates to a double tab metal fastener for securing a ridge strap or hip strap on a metal roof covering of the type with a standing seam, comprising:—a first tab (1) forming at one of its ends a hook (2) intended to be secured to the standing seam;—a second tab (3) forming at one of its ends a hook (4) intended to accept an edge of the ridge or hip strap; the two tabs being articulated about an axis (5) allowing their respective rotation in a plane intended to lie substantially parallel to the plane of the roof. This double tab represents a retaining system that can be used for ridging and hipping, which is easy to fit, without any through-fasteners, thus guaranteeing perfect sealing.

Abstract: In roof covering systems using zinc or zinc-alloy trays with standing-seam crimping, the use of tabs secured by two screws is well known. The invention particularly relates to a metal fastening tab for securing a standing-seam tray on a wood or wood-derivative carrier, which comprises a first surface (1) with a perforation (2) for receiving a screw for attachment onto the carrier, a second surface (3) generally perpendicular to said first surface and including a hook (4) for engaging with the ridge of the tray to be secured, the two surfaces defining an edge (5), characterised in that the first surface includes a single perforation (2) for receiving a single screw, and in that the centre (6) of said perforation (2) is not included in the mediator (7) of the edge (5) in order to reduce the force applied on the tab and on the tray by the torque induced when tightening said screw. Such a tab, with a single large-diameter screw, is easier and quicker to place than traditional tabs.
