The installation system comprises an installation element comprising a large diameter socket and a small diameter socket. The installation element is screwed to guide bolt through its large diameter socket. Passing through a hole on the water tank and a slot, a bolt is screwed into the small diameter socket of the element. The installation system ensures that the water tank is uninstalled from and installed to the toilet bowl without removing the toilet bowl from where it is installed. ## Claims ### Claim 1 An installation system (A) for installing a water tank (B) to a toilet bowl (C) characterized in that it comprises at least one guide bolt (5) which is inserted in an installation hole (C1) provided on the toilet bowl (C) and which comprises at least one slot (5a); at least one installation element (6) which comprises at least two screw sockets having different diameters and which is secured to the guide bolt (5) through the large diameter screw socket (7a); at least one bolt (1) which is screwed to the small diameter screw socket (8a) of the installation element (6) by passing through at least one installation hole (B1) provided on the water tank and the said slot (5a). ### Claim 2 (depends on 1) An installation system (A) according to claim 1 characterized in that the said installation element (6) comprises at least one guide nut (7) and at least one nut (8) which are engaged with each other. ### Claim 3 (depends on 2) An installation system (A) according to claim 2 characterized in that the guide nut (7) comprises a large diameter socket (7a). ### Claim 4 (depends on 2) An installation system (A) according to claim 2 characterized in that the said nut (8) comprises a small diameter socket (8a). ### Claim 5 (depends on 2) An installation system (A) according to claim 2 characterized in that the said guide nut (7) comprises at least one claw (7b). ### Claim 6 (depends on 2) An installation system (A) according to claim 2 characterized in that the said nut (8) comprises at least one claw (8b). ### Claim 7 (depends on 1) An installation system (A) according to claim 1 characterized in that the said installation element (6) is single piece. ### Claim 8 (depends on 1) An installation system (A) according to claim 1 characterized in that the said guide bolt (5) comprises at least one shoulder (5b) which extends in an axis different from the longitudinal axis of the bolt (5). ### Claim 9 (depends on 1) An installation system (A) according to claim 1 characterized by comprising at least one washer (2a) which is engaged with the said guide bolt (5). ### Claim 10 (depends on 1) An installation system (A) according to claim 1 characterized by comprising at least one washer (2b) which is engaged with the said bolt (1). ### Claim 11 (depends on 1) An installation system (A) according to claim 1 characterized by comprising at least one sealing element (3) which is engaged with the said bolt (1). ### Claim 12 (depends on 11) An installation system (A) according to claim 11 characterized in that the said sealing element (3) is conical. ### Claim 13 (depends on 1) An installation system (A) according to claim 1 characterized by comprising at least one fastening element (4) which secures the said guide bolt (5) to the installation hole of the toilet bowl (C1). ### Claim 14 (depends on 1) An installation system (A) according to claim 1 characterized by comprising at least one other fastening element which keeps the guide bolt (5) in the installation hole of the toilet bowl (C1).
