 the retaining device is arranged in the passage,   the passage has means for accommodating the retaining device and/or the retaining device has means for being accommodated in the passage, and   the means for accommodating or the means to be accommodated allowing a positioning adjustable in defined intervals or a continuously adjustable positioning of the retaining device in the passage.   
     
     
         27 . Tongue according to  claim 26 , wherein the adjustable positioning of the retaining device takes place at any position in the passage in intervals of 2.5 mm. 
     
     
         28 . Tongue according to  claim 23 , wherein the retaining device comprises at least one Tanka. 
     
     
         29 . Tongue according to  claim 24 , wherein in the basic structure an inlet opening and an outlet opening for passing through the tie are provided such that the tie is passed through between the inlet opening and the outlet opening on the bottom side of the basic structure and in the cavity. 
     
     
         30 . Tongue according to  claim 23 , where the tongue has a one-membered structure or a multi-membered structure. 
     
     
         31 . Tongue according to  claim 23 , wherein the essentially non-elastic material of the basic structure is plastic, in particular extruded polyurethane. 
     
     
         32 . Closing system for shoes comprising:
 a tongue according to  claim 23 ,   at least one tie and   guiding elements for the at least one tie on at least one side of a shoe-upper in which the at least one tie engages above the tongue, wherein in addition the at least one tie is fixedly received in a retaining device.   
     
     
         33 . Closing system according to  claim 32 , wherein the at least one tie is selected from bands, cords and gripping arms. 
     
     
         34 . Closing system according to  claim 32 , wherein the guiding elements are selected from eyelets and hooks. 
     
     
         35 . Closing system according to  claim 32 , wherein
 the retaining device is attached in a predefined position at a proximal end of the tongue and comprises two Tankas,   the padding is embodied such that a cavity is created,   in the basic structure, an inlet opening and an outlet opening for passing through the tie are provided such that the tie is guided through between the inlet opening and the outlet opening at the bottom side of the basic structure and in the cavity, and   two ties having the form of cords are provided such that a two-part tying is created wherein a distal cord extends substantially above the distal portion of the tongue, a proximal cord extends substantially above the proximal portion of the tongue and the distal cord is inserted into the inlet opening for bridging the portion of the proximal cord, is passed through at the bottom side of the tongue and in the cavity and is passed out of the outlet opening after bridging the portion of the proximal cord.   
     
     
         36 . Closing system according to  claim 35 , where the guiding elements are formed as eyelets and/or hooks and the proximal guiding elements are arranged at a distance of approximately 1.5 cm in the distal direction from the retaining device. 
     
     
         37 . Closing system according to  claim 32  wherein
 the retaining device is arranged in the passage, and 
 two guiding elements having the form of bars extend from proximal to distal at the left and the right shoe-upper and are arranged in proximal and distal seats. 
 
     
     
         38 . Closing system according to  claim 37 , wherein at the proximal and/or the distal seats adjustment devices for adjusting the position of at least one of the two bars are provided.
