A method and products for forming an interlocking push-in coupling between a first polymer containing product having a protrusion and a second polymer containing product having a hollow section by means of a fastening device comprising - a base plate having a first pair of opposite sides, a second pair of opposite sides, a first surface and a second surface; - a first pair of blade elements extending from sides of the first pair of the opposite sides; - a second pair of blade elements extending from sides of the second pair of the opposite sides, wherein the first pair of blade elements is connected to the base plate by a first pair of flexible joints forming a first acute angle between the normal of the first surface and the second pair of blade elements is connected to the base plate by a second pair of flexible joints forming a second acute angle between the normal of the second surface. |
