An assembly for axial fixation of at least one element having an opening formed therein to an article. The assembly includes an anchoring protrusion attached to the article, which includes a distal end and a neck portion, and at least one locking component having a bore disposed therein, the locking component having at least a portion which is at least one of flexible and elastic. The anchoring protrusion extends through the opening in the element and through the bore of the locking component. An overlap region between the opening of the element and the bore of the locking component, is substantially equal to the diameter of the neck portion, such that the element and the at least a portion of the locking component form a locking unit.
