A system for painting objects (9; 109), in particular vehicle bodies, comprising a) a painting booth (1; 101); b) at least one application device (7; 107) arranged in the painting booth (1; 101), from which paint can be discharged onto the objects (9; 109); c) a plurality of ring lines (16; 116), which extend along the painting booth (1; 101) and each carry an operating medium needed for the operation of the application device (7; 107), in particular a paint of a specific color or a purging liquid or air; d) at least one connecting device (17-24; 177-124), via which at least some of the ring lines (16; 116) can be connected to the application device (7; 107) as required; characterized in that e) each ring line (16; 116) is subdivided into at least two ring line regions (16a; 116a); f) the connecting device (17-24; 117-124) has at least one factory-prefabricated terminal module (17; 117), which in turn comprises: fa) at least as many ring line sections (19; 119) as there are ring lines (16; 116), which have terminals (20; 120) at their ends to connect to the ring line regions (16a; 116a); fb) for each ring line section (19; 119), a branch line (21; 1212) branching off from the latter; fc) a terminal device (22, 122), to which the branch lines (21; 121) lead and via which at least some of the branch lines (21; 121) can be connected to an outlet terminal; g) at least one hose or a line (23; 123) connects the outlet terminal (27; 127) of the terminal module (17; 117) directly or indirectly to the application device (7; 107). a) a painting booth (1; 101); b) at least one application device (7; 107) arranged in the painting booth (1; 101), from which paint can be discharged onto the objects (9; 109); c) a plurality of ring lines (16; 116), which extend along the painting booth (1; 101) and each carry an operating medium needed for the operation of the application device (7; 107), in particular a paint of a specific color or a purging liquid or air; d) at least one connecting device (17-24; 177-124), via which at least some of the ring lines (16; 116) can be connected to the application device (7; 107) as required; characterized in that e) each ring line (16; 116) is subdivided into at least two ring line regions (16a; 116a); f) the connecting device (17-24; 117-124) has at least one factory-prefabricated terminal module (17; 117), which in turn comprises: fa) at least as many ring line sections (19; 119) as there are ring lines (16; 116), which have terminals (20; 120) at their ends to connect to the ring line regions (16a; 116a); fb) for each ring line section (19; 119), a branch line (21; 1212) branching off from the latter; fc) a terminal device (22, 122), to which the branch lines (21; 121) lead and via which at least some of the branch lines (21; 121) can be connected to an outlet terminal; fa) at least as many ring line sections (19; 119) as there are ring lines (16; 116), which have terminals (20; 120) at their ends to connect to the ring line regions (16a; 116a); fb) for each ring line section (19; 119), a branch line (21; 1212) branching off from the latter; fc) a terminal device (22, 122), to which the branch lines (21; 121) lead and via which at least some of the branch lines (21; 121) can be connected to an outlet terminal; g) at least one hose or a line (23; 123) connects the outlet terminal (27; 127) of the terminal module (17; 117) directly or indirectly to the application device (7; 107).
