A system for sheathing a building facade, which system comprises a plurality of mounting rails (2,2'), and a plurality of facade elements (1,1'), wherein - each mounting rail (2,2') comprises, viewed in cross section of the mounting rail's longitudinal direction, an abutment part, which is suitable for abutting against the building facade, as well as a first supporting protrusion and a second supporting protrusion, wherein each supporting protrusion (21,22) further comprises an abutment surface (23, 24) for abutting the facade elements, and wherein the abutment surface is shaped at a first distance from the abutment part, while the second abutment surface is shaped at a second distance, and wherein the second distance is smaller than the first distance; - each facade element (1,1') comprises a first groove and a second groove, arranged for retaining one or more facade elements (1,1') relative to the mounting rail (2,2'), a front configured to be facing away from the mounting rail (1,1') and a backside configured to be facing towards the mounting rail (1,1'), wherein the backside comprises one or more projecting parts, wherein a first projecting part comprises the first groove, and which system is suitable for being mounted in a first configuration, wherein the facade elements are mounted in parallel with the building facade (b), so that the front of the facade elements extends substantially in the same plane when mounted on a plane building surface or in a second configuration, wherein the facade elements are mounted so that they form an angle relative to a plane surface on the building facade, and wherein the facade elements (1,1') partially overlap each other, characterised in that the system comprises a plurality of clips, wherein each of the mounting clips comprises a grappler arm and a facade part connected via a clip joint, whereby the grappler arm and the facade part can be rotated pivotably relative to each other about the clip joint from a first end position to a second end position via deformation of the joint, wherein the grappler arm is suitable for mounting the mounting clip on one of the mounting rails (2, 2') and the facade part is arranged to support the backside of a facade element (1, 1') and to press the facade element (1, 1') towards the front of the facade element (1, 1') due to deformation of the clip joint. - each mounting rail (2,2') comprises, viewed in cross section of the mounting rail's longitudinal direction, an abutment part, which is suitable for abutting against the building facade, as well as a first supporting protrusion and a second supporting protrusion, wherein each supporting protrusion (21,22) further comprises an abutment surface (23, 24) for abutting the facade elements, and wherein the abutment surface is shaped at a first distance from the abutment part, while the second abutment surface is shaped at a second distance, and wherein the second distance is smaller than the first distance; - each facade element (1,1') comprises a first groove and a second groove, arranged for retaining one or more facade elements (1,1') relative to the mounting rail (2,2'), a front configured to be facing away from the mounting rail (1,1') and a backside configured to be facing towards the mounting rail (1,1'), wherein the backside comprises one or more projecting parts, wherein a first projecting part comprises the first groove, and which system is suitable for being mounted in a first configuration, wherein the facade elements are mounted in parallel with the building facade (b), so that the front of the facade elements extends substantially in the same plane when mounted on a plane building surface or in a second configuration, wherein the facade elements are mounted so that they form an angle relative to a plane surface on the building facade, and wherein the facade elements (1,1') partially overlap each other, characterised in that the system comprises a plurality of clips, wherein each of the mounting clips comprises a grappler arm and a facade part connected via a clip joint, whereby the grappler arm and the facade part can be rotated pivotably relative to each other about the clip joint from a first end position to a second end position via deformation of the joint, wherein the grappler arm is suitable for mounting the mounting clip on one of the mounting rails (2, 2') and the facade part is arranged to support the backside of a facade element (1, 1') and to press the facade element (1, 1') towards the front of the facade element (1, 1') due to deformation of the clip joint.
