The invention claimed is: 1. Delivery system for fluid substances, which comprises a plunger-type syringe in the form of a cartridge having at least one fluid chamber, which fluid chamber is provided with an injection plunger, and an attachment mounted on the cartridge at its delivery-side end and a locking clip which is arranged between a cartridge and the attachment and, locked with the cartridge, wherein the attachment is mounted on the locking clip by means of a releasable snap closure; the cartridge having at least two axially parallel, adjacently arranged fluid chambers having separate outlet openings; the locking clip including incomplete rings joined to one another by at least one rib-like element therebetween; each incomplete ring engaging around a separate outlet opening; and, the locking clip including resilient arms projecting from the incomplete rings wherein each resilient arm of one incomplete ring projecting in the direction towards the other incomplete ring. 2. Delivery system according to claim 1, wherein there are formed on the attachment, for the purpose of its being mounted on the cartridge, two hooks which are arranged substantially diametrically opposite; and the two resilient arms are resiliently biased on being deflected out of their rest position, each of which is provided with an undercut groove arranged facing a hook, the hooks engaging in the undercut grooves facing them. 3. Delivery system according to claim 1, wherein the resilient arms are in the form of portions of the locking clip mounted on the delivery-side end of the cartridge. 4. Delivery system according to claim 1 wherein the attachment is a closure cap for closing the outlet openings of the fluid chambers. 5. Delivery system according to claim 1 wherein the attachment has no rotational symmetry about axes of rotation in the longitudinal direction of the cartridge. 6. Delivery system according to claim 1 wherein the snap closure locks into place with an audible sound. 7. Delivery system for fluid substances, which comprises a plunger-type syringe in the form of a cartridge having at least one fluid chamber, which fluid chamber is provided with an injection plunger; a locking clip selectively mountable on the cartridge at its delivery-side end; an attachment selectively mountable on the locking clip by means of a releasable snap closure wherein the attachment including two hooks which are arranged substantially diametrically opposite for the purpose of its being mounted on the locking clip; the locking clip including two resilient arms which are resiliently biased on being deflected out of their rest position, each of which is provided with an undercut groove arranged facing one of the two hooks, the hooks engaging in the undercut grooves facing them; and, wherein the resilient deflection of the resilient arms includes providing the resilient arms with pressure faces in the form of planar widened portions, the hooks becoming disengaged from the undercut grooves by exertion of a sufficient pressing force on the pressure faces. 8. Delivery system for fluid substances, which comprises a plunger-type syringe in the form of a cartridge having at least one fluid chamber, which fluid chamber is provided with an injection plunger, and an attachment mounted on the cartridge at its delivery-side end and a locking clip which is arranged between a cartridge and the attachment and, locked with the cartridge, wherein the attachment is mounted on the locking clip by means of a releasable snap closure; wherein there are formed on the attachment, for the purpose of its being mounted on the cartridge, two hooks which are arranged substantially diametrically opposite; and there are formed on the delivery-side end of the cartridge two resilient arms which are resiliently biased on being deflected out of their rest position, each of which is provided with an undercut groove arranged facing a hook, the hooks engaging in the undercut grooves facing them; the resilient arms are in the form of portions of a locking clip mounted on the delivery-side end of the cartridge; and, wherein the locking clip takes the form of incomplete rings which engage around the outlet openings of the cartridge and are joined to one another by at least one rib-like element, having resilient arms which project from the incomplete rings, which resilient arms can take each other's places by rotation of the cartridge through 180�� about its longitudinal axis. 9. Delivery system for fluid substances, which comprises a plunger-type syringe in the form of a cartridge having at least one fluid chamber, which fluid chamber is provided with an injection plunger, and an attachment mounted on the cartridge at its delivery-side end and a locking clip which is arranged between a cartridge and the attachment and, locked with the cartridge, wherein the attachment is mounted on the locking clip by means of a releasable snap closure; wherein there are formed on the attachment, for the purpose of its being mounted on the cartridge, two hooks which are arranged substantially diametrically opposite; and there are formed on the delivery-side end of the cartridge two resilient arms which are resiliently biased on being deflected out of their rest position, each of which is provided with an undercut groove arranged facing a hook, the hooks engaging in the undercut grooves facing them; and, wherein the resilient deflection of the resilient arms includes providing the resilient arms with pressure faces in the form of planar widened portions, the hooks becoming disengaged from the undercut grooves by exertion of a sufficient pressing force on the pressure faces. 10. Delivery system according into claim 9, wherein the pressure faces lie substantially diametrically opposite one another.
