摘要

The system (10) has a slot determined by a receiving surface (21) of a flap (12) and by an elastically flexible retention wall (22). The slot has a height that is slightly lower than a thickness of a part of the flap to be engaged across the slot. The wall is moved such that the wall is obliterated during introduction of the part of the flap in the slot. The wall is carried against the part of the flap by pinching the part of the flap between the wall and the surface in a manner to retain the part of the flap between the wall and the surface.
