1. A clip applicator comprising, first housing means for storing a plurality of clips, second housing means including jaw means which are selectively expandable, said first housing means disposed in engagement with said second housing means and adapted to selectively supply individual clips to said jaw means whereby said clips can be selectively expanded by said jaw means, and ramp means mounted in said second housing means, said jaw means mounted in sliding relationship to said ramp means whereby said jaw means is selectively expanded. 2. The clip applicator recited in claim 1 including, resilient means in said first housing means for urging said clips in a prescribed direction. 3. The clip applicator recited in claim 1 including, trigger means mounted in said second housing means and adapted to engage said jaw means. 4. The applicator recited in claim 3 wherein, said trigger means is pivotally mounted to said second housing and selectively causes said jaw means to slide relative to said second housing when said trigger means is actuated. 5. The clip applicator recited in claim 2 wherein, said resilient means comprises a coiled spring. 6. The clip applicator recited in claim 2 wherein, said resilient means is connected to one end of said first housing means. 7. The clip applicator recited in claim 1 wherein, said jaw means includes a first jaw member and a second jaw member, said first and second jaw members pivotally mounted to each other. 8. The clip applicator recited in claim 1 including, door means at the front end of second housing means through which clips are selectively passed by said jaw means. 9. The clip applicator recited in claim 8 wherein, said door means is spring loaded to the closed position at the front end of said second housing. 10. The clip applicator recited in claim 1 including, sear means pivotally mounted in said second housing means, said sear means adapted to selectively engage said ramp means thereby to position said ramp means relative to said jaw means. 11. The applicator recited in claim 1 wherein, said first housing has a generally rectilinear cross-section. 12. The applicator recited in claim 11 wherein, said first housing is curved at one end thereof to direct the clips stored therein in a preferred direction. 13. The applicator recited in claim 12 wherein, said first housing is latched to said second housing so that clips stored in said first housing are selectively transferred into said second housing. 14. The applicator recited in claim 12 wherein, said second housing has a stepped configuration to accommodate said curved first housing. 15. The cips applicator recited in claim 1 wherein, said clips are independent of each other. 16. The clip applicator recited in claim 1 wherein, said clips are hemostasis clips. 17. The clip applicator recited in claim 1 wherein, said ramp means is pivotally mounted within said second housing. 18. The clip applicator recited in claim 17 wherein, said ramp means includes resilient means to selectively force said ramp means downwardly relative to said second housing. 19. A clip applicator comprising, a magazine for retaining a plurality of resilient clips, a support device for supporting said magazine thereon, and a pair of opposed jaws slidably mounted at said support device, said pair of opposed jaws adapted to engage individual clips and to expand relative to said support device thereby to expand said clips. 20. The applicator recited in claim 19 wherein, said clips include an aperture in a closed end thereof which receives said pair of opposed jaws. 21. The applicator recited in claim 19, wherein, each of said jaws include a lip which extends from the end thereof and engages said clips. 22. The applicator recited in claim 19 wherein, said pair of opposed jaws extend beyond said support device when in engagement with said clips. 23. The applicator recited in claim 19 including, clip locator means mounted in said support device to receive clips from said magazine and position same relative to said pair of opposed jaws. 24. The applicator recited in claim 23 wherein, said clip locator means is spring loaded into position to receive said clips, said clip locator means is pivotally mounted to be selectively moved out of said position when said jaws slide relative to said support device. 25. The applicator recited in claim 19 including, latch means for selectively attaching said magazine to said support device. 26. The applicator recited in claim 19 wherein, said magazine includes a ledge formed in at least one sidewall thereof for cooperating with said clips in order to maintain said clips in a preferred orientation. 27. The applicator recited in claim 26 wherein, said clips include a shoulder at at least one side thereof to cooperate with said ledge. 28. The applicator recited in claim 19 wherein, said pair of opposed jaws is pivotally mounted to each other. 29. The applicator recited in claim 28 includes, a spring member interposed between said pair of opposed jaws to urge the front end of said jaws toward each other. 30. The applicator recited in claim 19 including, spacer means interposed between said pair of opposed jaws to determine the minimum spacing therebetween. 31. Clip means comprising, a coiled sheet of resilient material having a closed end, an open end with abutting edges and a pair of substantially parallel sides between said open and closed ends, said abutting edges having at least a portion thereof which is rugose, said closed end having an aperture therethrough, and an idented shoulder in at least one of said sides of said coiled sheet, intermediate said closed end and open end. 32. The clip means recited in claim 31 wherein, said abutting edges are spaced apart. 33. The clip means recited in claim 31 wherein, said coiled sheet of resilient material has a generally ovoid configuration.
