An injector system includes an injector and a syringe. The injector includes a housing having a front wall, a drive member moveable through the front wall of the housing, and a pressure jacket assembly for operably associating the syringe with the housing. The pressure jacket assembly includes a rearward end mounted on the front wall of the housing and a forward open end for receiving the syringe therethrough. The syringe includes a body having a main section, a conical section in fluid communication with the main section and a fluid discharge section in fluid communication with the conical section. The syringe further includes a plunger movably disposed in the body. The plunger includes one or more hook members extending rearward from the plunger for connecting the plunger to the drive member of the injector. The syringe also includes a protrusion for facilitating handling of the syringe. Preferably, the protrusion is operably associated with and extends forwardly from the conical section of the body.
