The system as claimed in claim 1, wherein at least one of the two clamping surfaces extends around the axis of rotation over an angular range of less than 360° and the other clamping surface extends over less than the remaining angular range around the axis of rotation; the tightening element is rotatable relative to both the spraying implement and the support between an angular position of separation, where the clamping surfaces are in adjacent and non-overlapping angular ranges, and an angular position of clamping, where the two clamping surfaces overlap at least partly and are clamped together; and the other of the spraying implement and the support to which the tightening element is not affixed has a recess which defines a passage through which the tightening element is rotatable between the angular position of separation and the angular position of clamping to move the clamping surfaces towards and away from each other in the longitudinal direction of the axis of rotation. 3. The system as claimed in claim 1, wherein at least one of the clamping surfaces is rising like a thread toward the other clamping surface within a partial range around the axis of rotation. 4. The system as claimed in claim 1, wherein the tightening element includes a handle for manual operation. 5. The system as claimed in claim 4, wherein the handle is a lever running transversely from the axis of rotation and ending at an end located beyond the other of the spraying implement and the support which has the second clamping surface, so that said end is externally manually accessible. 6. The system as claimed in claim 1, wherein the relative angle of rotation of the two clamping surfaces between the angular position of clamping and the angular position of separation is equal to or less than 180°. 7. The system as claimed in claim 1, wherein a latch is constituted between the spraying implement and the support and runs in an assembling direction of the spraying implement and the support transverse to the axis of rotation when the tightening element assumes the angular position of separation. 8. The system as claimed in claim 7, wherein the latch and the tightening element are configured radially to the axis of rotation at a mutual distance that runs at least beyond one of the seals. 9. The system as claimed in claim 7, wherein the latch comprises a first latch surface provided by the spraying implement and a second latch surface provided by the support, said two latch surfaces being configured away from the axis of rotation and mutually opposite in the longitudinal direction of the axis of rotations; the first latch surface of the spraying implement faces away from the fluid-transmitting duct ends of said first fluid-transmitting ducts; and the second latch surface of the support faces away from the fluid-transmitting duct ends of said second fluid-transmitting ducts. 10. The system as claimed in claim 9, wherein no gap or only a gap less than 1.0 mm is present between the latch surfaces when the spray implement and the support and the seals therebetween are superposed in the absence of compression by the tightening element. 11. The system as claimed in claim 9, wherein at least one of the latch surfaces is provided by an offset or protrusion running in the direction between the axis of rotation of the tightening element and the latch. 12. The system as claimed in claim 7, wherein the latch is configured at a radial distance from the axis of rotation outside the fluid-transmitting duct ends. 13. The system as claimed in claim 7, wherein the axis of rotation and the latch are positioned on opposite sides of the fluid-transmitting duct ends. 14. A spray-coating system, comprising: a spraying implement having at least one first fluid-transmitting duct; a support having at least one second fluid-transmitting duct; a tightening element which is rotatably attached to one of the spraying implement and the support for detachably affixing said support to said spraying implement, said tightening element comprising a first clamping surface, the other of the spraying implement and the support comprising a second clamping surface; said first and second fluid-transmitting ducts having first and second fluid-transmitting duct ends, respectively, said first fluid-transmitting duct ends being configured opposite said second fluid-transmitting duct ends, when said spraying implement is affixed to said support by said tightening element, to allow fluid transmission between said first and second fluid-transmitting ducts; and at least one seal between said first and second fluid-transmitting duct ends to mutually seal the support and the spraying implement, said seals being compressible between the spraying implement and the support when said spraying implement is affixed to said support by said tightening element; wherein the tightening element has an axis of rotation and is rotatable about said axis of rotation between an angular position of separation and an angular position of clamping; and a movement of said tightening element from said angular position of separation to said angular position of clamping brings the first and second clamping surfaces towards each other in the direction of said axis of rotation, so as to clamp the spraying implement against the support, thereby compressing the seal between the spraying implement and the support. 15.
