Luer-snap connection and luer-snap syringe

A syringe comprising:

• a barrel including a sidewall having an inside surface defining a chamber for retaining fluid, an open proximal end and a distal end including a distal wall having a luer tip with an opening therethrough in fluid communication with said chamber;
• a collar extending from the distal wall, the collar in a coaxial relationship with the luer tip defining a channel for receiving a needle hub therein and having a distal end and a proximal end with an open slot disposed therebetween;
• a rotatable arm extending from the collar including a pivot portion, an arm portion extending radially outwardly from the pivot portion and a latch extending radially inwardly from the pivot portion for engagement with a lip portion of the needle hub to permit assembly of the needle hub and the collar in a snap-fit relationship without relative rotation between the needle hub and the barrel, wherein upon engagement of the pivot portion of the rotatable arm with the lip portion of the needle hub the lip portion extends through the open slot of the collar to prevent rotation of the needle hub relative to the collar;
• and
• an elongate plunger rod including a proximal end, a distal end having a stopper and an end wall, the stopper in a fluid-tight engagement with the inside surface of the barrel, and a main body extending between the proximal and distal end, the plunger rod being distally and proximally movable within said chamber.
