         2 . The kit ( 1 ) according to  claim 1 , wherein the adapter element ( 5 ) has, in the area of an end face ( 11 ) that can be guided in the connection element ( 3 ), a sealing means ( 12 ) for sealing with respect to the inner surface ( 4 ) of the connection element ( 3 ). 
     
     
         3 . The kit ( 1 ) according to  claim 1 , wherein a screw connection is formed between the outer surface ( 7 ) of the adapter element ( 5 ) and an inner surface ( 13 ) of the connecting element ( 10 ), by means of which screw connection the longitudinal position of the adapter element ( 5 ) can be changed relative to the connection element ( 3 ). 
     
     
         4 . The kit ( 1 ) according to  claim 1 , wherein the connecting element ( 10 ) is set up such that it secures the adapter element ( 5 ) in a longitudinal position relative to the connection element ( 3 ) until a predeterminable minimum torque is applied to the adapter element ( 5 ). 
     
     
         5 . The kit ( 1 ) according to  claim 1 , wherein a female thread ( 15 ) is formed on an inner surface ( 14 ) of the adapter element ( 5 ), by means of which the adapter element ( 5 ) can be screwed to the sanitary faucet connection ( 9 ) in such a way that the longitudinal position of the sanitary faucet connection ( 9 ) can be changed relative to the adapter element ( 5 ). 
     
     
         6 . The kit ( 1 ) according to  claim 1 , wherein the kit ( 1 ) further comprises a box ( 16 ) in which at least the connection element ( 3 ), the adapter element ( 5 ) and the connecting element ( 10 ) can be arranged. 
     
     
         7 . A system ( 17 ) for installing a sanitary faucet ( 2 ) on a water connection arranged flush-mounted or behind a pre-wall element, comprising at least the sanitary faucet ( 2 ) and a kit ( 1 ) according to  claim 1 . 
     
     
         8 . The system ( 17 ) of  claim 7 , further comprising a body ( 18 ) for at least partially mounting the sanitary faucet ( 2 ), wherein the sanitary faucet connector ( 9 ) is disposed on the body ( 18 ) and directed away from the sanitary faucet ( 2 ), and wherein the body ( 18 ) and the kit ( 1 ) interact such that rotational motion of the body ( 18 ) causes a change in longitudinal position of the body ( 18 ) relative to the sanitary faucet. 
     
     
         9 . A method for installing a sanitary faucet ( 2 ) on a water connection arranged flush-mounted or behind a pre-wall element by means of a kit ( 1 ) using a connection element ( 3 ), an adapter element ( 5 ) and a connecting element ( 10 ), comprising at least the steps outlined below:
 a) connecting the connection element ( 3 ), which has an inner surface ( 4 ) for guiding the adapter element ( 5 ) in a longitudinal direction ( 6 ), to the water connection,   b) arranging the adapter element ( 5 ), which has an outer surface ( 7 ) matching the inner surface ( 4 ) of the connection element, such that the adapter element ( 5 ) can be guided by the connection element ( 3 ) in the longitudinal direction ( 6 ),   c) securing the adapter element ( 5 ) relative to the connection element ( 3 ) by means of the connecting element ( 10 ), which is detachably connected to the connection element ( 3 ) for this purpose, wherein the connecting element ( 10 ) is set up in such a way that it can guide the adapter element ( 5 ) in the longitudinal direction ( 6 ),   d) connecting a sanitary faucet connection ( 9 ) of the sanitary faucet ( 2 ) to a connecting means ( 8 ) of the adapter element ( 5 ).   
     
     
         10 . A use of a kit ( 1 ) according to  claim 1  for installing a sanitary faucet ( 2 ) on a water connection arranged flush-mounted or behind a pre-wall element.
