Patent Claims:	1. A plastic adaptor top for mounting on a standard cartridge of the kind having a neck part with a flange and being closed by a rubber membrane sealingly secured against the flange by a metal cover having its edge beaded behind the flange, said adaptor top comprising: an axially extending bore (2) having a diameter conforming to the diameter of the metal cover of such standard cartridge and having at least one radially inwardly extending protrusion, the top being made of plastic material which may be deformed to allow the said at least one protrusion to be pressed radially outwardly when the neck part of a cartridge is pressed into the bore (2), to pass over the metal cover of such standard cartridge, and wherein said at least one protrusion is positioned axially within said bore so as to grip behind the beaded edge of such metal cover, after such metal cover is pressed into said bore to secure said adaptor top to the metal cover, and wherein said adaptor top has an outer contour suitable to be received in and engage an interior portion of a syringe for positioning such standard cartridge therewithin, said adaptor top thereby being suitable to make a standard cartridge usable in a syringe which it otherwise would not fit. 2. The adaptor top according to claim 1, further comprising a thread (5, 18) coaxial with the bore (2) which thread is provided as an outer thread on the outer contour of the plastic top. 3. A plastic adaptor top for mounting on a standard cartridge of the kind having a neck part with a flange and being closed by a rubber membrane sealingly secured against the flange by a metal cover having its edge beaded behind the flange, said adaptor top comprising: an axially extending bore (2) having a diameter conforming to the diameter of the metal cover of such standard cartridge, wherein said adaptor top has an outer contour suitable to be received in and engage an interior portion of a syringe for positioning such standard cartridge therewithin, said adaptor top thereby being suitable to make a standard cartridge usable in a syringe which it otherwise would not fit, wherein said outer contour comprises interlocking means for interlocking engagement with corresponding means in a syringe to prevent rotation of said adaptor top when said adaptor top is inserted into such a syringe and wherein said adaptor top further comprises a thread coaxial with the bore to receive a threaded needle hub. 4. The adaptor top according to claim 3, wherein said interlocking means are knobs (7) at the lower end of the top, said knobs (7) having triangular cross-sections with an apex directed upwardly. 5. The adaptor top in accordance with claim 1 for use with a standard insulin cartridge which may contain one of various types of insulin, wherein said adaptor top is colored in accordance with a color code system in which each color indicates a particular type of insulin such that said adaptor top, when mounted on a standard insulin cartridge indicates the type of insulin contained in such cartridge.
