1. A method of manufacturing a syringe comprising:
injection molding a syringe barrel having a distal end, a distal tip, an open proximal end, a sidewall extending between the distal end to the open proximal end, the sidewall defining a chamber, the distal end of the syringe barrel including a distal wall; and a connector integrally formed with and extending distally from the syringe barrel at the distal wall, the connector including a collar disposed coaxially around an elongate tip in fluid communication with the barrel to form a channel between the elongate tip and the collar, the collar including an inside surface, an outside surface and a plurality of ribs extending from the distal wall of the syringe barrel towards the distal tip and extending radially outwardly from the outside surface and the plurality of ribs separated by spaces, each of the plurality of ribs having a height H and a width W, wherein there is a ratio of height H to the barrel sidewall thickness t in a range of 0.75 and 1, wherein each of the plurality of ribs curves from the distal wall to the distal tip.
