         6 . The device according to one of  claims 1  to  5 , wherein the complementary profiles ( 110   a - 110   e ,  210   a - 210   e ) include profiles of male/male type. 
     
     
         7 . The device according to one of  claims 1  to  5 , wherein at least one part of the complementary profiles ( 110   a - 110   c ,  210   a - 210   c ) is made of a first material, and at least one other part of the complementary profiles ( 110   d - 110   e ,  210   d - 210   e ) is made of a second material, different to the first material. 
     
     
         8 . The device according to  claim 7 , wherein the first material includes polypropylene or high-density polyethylene, and the second material includes polyethylene or low-density polyethylene. 
     
     
         9 . The device according to one of  claim 7  or  8 , wherein the complementary profiles ( 110   a - 110   c ,  210   a - 210   c ) including sequential alterations are made of the first material. 
     
     
         10 . The device according to one of  claims 7  to  9 , including both complementary profiles ( 110   a - 110   c ,  210   a - 210   c ) including sequential alterations ( 300 ) and complementary profiles ( 110   d - 110   e ,  210   d - 210   e ) devoid of sequential alterations, and wherein the complementary profiles ( 110   d - 110   e ,  210   d - 210   e ) devoid of sequential alterations ( 300 ) are made of the second material.
