An injector mount clamp for coupling an injector of an exhaust gas treatment system to an exhaust conduit of an engine while the conduit is in an installed position includes a resilient monolithic clamp body having an aperture extending therethrough and being shaped as a split collar having a first end spaced apart from a second end a distance allowing the clamp body to be transversely moved relative to an exhaust flow direction to a position circumferentially surrounding the exhaust conduit. An injector mounting boss is disposed on the clamp body and defines a passage that fluidly communicates with the aperture of the clamp body. The mounting boss has a mounting face configured to oppose the injector.

1. An injector mount clamp for coupling an injector of an exhaust gas treatment system to an exhaust conduit of an engine while the conduit is in an installed position, the injector mount clamp comprising: a resilient monolithic clamp body having an aperture extending therethrough and being shaped as a split collar having a first end spaced apart from a second end a distance allowing the clamp body to be transversely moved relative to an exhaust flow direction to a position circumferentially surrounding the exhaust conduit;an insulating material coupled to an inner surface of the clamp body to space apart the inner surface from the conduit and thermally insulate the clamp body from the conduit; andan injector mounting boss disposed on the clamp body and defining a passage that fluidly communicates with the aperture of the clamp body, the mounting boss having a mounting face configured to oppose the injector. 2. The injector mount clamp of claim 1, wherein the first and second ends each include a mounting ear extending therefrom, the mounting ears defining at least one complementary passage therethrough, the clamp including a fastener for moving the mounting ears closer to one another and reducing an inner diameter of the split collar. 3. The injector mount clamp of claim 2, wherein the mounting ears include complementary engaging surfaces that are configured to engage the conduit during the transverse movement. 4. The injector mount clamp of claim 1, wherein the passage of the boss is threaded and configured to threadably mate with complementary threads on the injector. 5. The injector mount clamp of claim 1, wherein the boss protrudes only radially outwardly from the clamp body. 6. The injector mount clamp of claim 1, wherein the injector mounting boss is welded to the clamp body. 7. The injector mount clamp of claim 6, wherein the clamp body is formed of stainless steel. 8. The injector mount clamp of claim 2, wherein the distance between the first and second ends is less than an outer diameter of the conduit such that the clamp body deflects radially outwardly to accommodate the exhaust conduit during an installation step and subsequently deflects radially inwardly to a position where the clamp body becomes fixed to the conduit. 9. An injector mount clamp for coupling an injector of an exhaust gas treatment system to an exhaust conduit of an engine while the conduit is in an installed position, the exhaust conduit having an opening, the injector mount clamp comprising: a clamp body having a first end and a second end, the clamp body having a generally circumferential profile configured to conform to the exhaust conduit, the clamp body having a thickness that defines an aperture;an insulating material configured to be located intermediate the clamp body and the exhaust conduit when the clamp is at an installed position, the insulating material uninterruptedly circumferentially extending from the first end of the clamp body to the second end of the clamp body to space apart the clamp body from the exhaust conduit; andan injector mounting boss disposed on the clamp body, the injector mounting boss having a cylindrical body portion and a flange, the cylindrical body portion defining a passage that fluidly communicates with the aperture of the clamp body, the flange having an outer mounting face configured to oppose a complementary flange on the injector such that a terminal end of the injector is in fluid communication with the exhaust conduit, without extending beyond an inner circumference of the exhaust conduit when in an installed position. 10. The injector mount clamp of claim 9, wherein the cylindrical body portion has a first inner diameter and the opening in the exhaust conduit has a second inner diameter, the second inner diameter being less than the first inner diameter. 11. The injector mount clamp of claim 9, wherein the first and second ends each have mounting ears extending therefrom, the mounting ears having complementary engaging surfaces that are configured to engage in the installed position. 12. The injector mount clamp of claim 11, wherein the mounting ears define at least one complementary passage therethrough configured to accept a fastener in the installed position. 13. The injector mount clamp of claim 12, wherein the passage of the cylindrical body portion is threaded and configured to threadably mate with complementary threads on the injector. 14. The injector mount clamp of claim 9, wherein the boss protrudes only radially outwardly from the clamp body. 15. The injector mount clamp of claim 11, wherein the thickness of the clamp body is configured to allow the clamp body to deflect radially outwardly to accommodate the exhaust conduit during an installation step and subsequently deflect radially inwardly to a position where the clamp body becomes fixed to the conduit. 16. A method for retrofitting an injector of an exhaust gas treatment system to an exhaust conduit of an engine, the method comprising: forming an opening in the exhaust conduit;advancing a clamp body of an injector mount clamp around the exhaust conduit in a direction transverse to the flow of exhaust through the conduit, the clamp body having a first end and a second end as well as an injector mounting boss disposed thereon, the mounting boss defining a passage in fluid communication with the opening in the exhaust conduit;advancing a fastener through apertures formed in complementary ears extending from the first and second ends of the clamp body;placing insulating material intermediate the clamp body and the exhaust conduit to space apart the clamp body from the exhaust conduit and reduce heat transfer therebetween;tightening the fastener relative to the clamp body to move the first and second ends of the clamp body closer to each other and inhibit slidable movement of the clamp body along the exhaust conduit; andadvancing an insertion end of the injector into the injector mounting boss until the injector engages the exhaust conduit. 17. The method of claim 16, wherein advancing the clamp body comprises radially expanding the clamp body until the ears extend beyond an outer diameter of the exhaust conduit and wherein tightening the fastener causes the clamp body to radially contract to a profile that conforms to the exhaust conduit. 18. The method of claim 16, wherein advancing the insertion end of the injector comprises threadably advancing the insertion end of the injector along complementary threads formed in the mounting boss. 19. The method of claim 18, further comprising terminating the advancing such that a terminal end of the injector engages the exhaust conduit, without extending beyond an inner circumference of the exhaust conduit. 20. The method of claim 16, wherein forming the opening in the exhaust conduit includes guiding a cutting tool through the passage defined by the mounting boss.
