Hooking coupling system and method of coupling thereof

Abstract

A coupling system comprising: a base plate; a first coupling element; a second coupling element; and a fixation means. The first coupling element is coupled to the base plate and comprises a first hooking part extending away from the base plate. The second coupling element is movably coupled to the base plate in a plane parallel to the base plate to allow altering a distance between the first second coupling elements. The second coupling element comprises a second hooking part extending away from the base plate. The first hooking part and the second hooking part are configured for cooperating with a coupling recess by hooking to an internal peripheral edge thereof after insertion. The fixation means is provided to the base plate and configured for, in a first position, retaining the second coupling element movably coupled, and for, in a second position, locking the second coupling element in position.
