Fastening means comprising an element (3) so arranged as to extend through a hole (11) in a wall (8), to which fastening is to be effected, and an organ (1, 6) situated on the inside of the wall. The organ is so arranged as to be capable of being introduced through the hole from the outside of the wall. The organ (1, 6) exhibits a washer (1) made of resilient material consisting of a ring-shaped strip coiled into the form of a spiral, the outer diameter of which is larger than that of the hole (11) in the wall, and the radial width of which between its outer and inner diameters is not greater than the diameter of the hole (11) in the wall. The washer is thus capable of being screwed in through the hole in such a way as to be centered on the hole on the inside of the wall. A securing component (6) is so arranged as to hold the element (3) securely in contact with the washer (1). The element is retained by the securing component being provided with support via the washer against the inside of the wall, at the same as the washer is in contact with said inside of the wall at the edge of the hole after it has been centered. |
