Claim 3:
4. The device as claimed in claim 1, wherein the protruding element (12) of each longitudinal edge is a cable in the form of consecutive turns forming a helical spring, the axis thereof being parallel to the corresponding longitudinal edge of the cover (10), wherein the turns are defined such that
in a resting configuration the minimum diameter (d), measured parallel to the transverse axis (Y) of each turn at rest, is equal to d0 which is between the maximum widths (Lo, Le) of the opening (14) and the space (14e) of the corresponding rail (Lo<d0<Le), and
in a deformed configuration, the angle formed by the deformed turns with the longitudinal axis (X) is changed such that the minimum diameter (d1) measured in a plane perpendicular to the longitudinal axis (X) of each deformed turn is less than or equal to the maximum width (Lo) of the opening (14) of the corresponding rail (d1≤Lo),, and wherein the insertion system makes it possible to deform locally the turns in their deformed configuration when inserted through the opening (14) of the corresponding rail (6), the turns recovering their resting configuration once they are located in the space (14e).
