Abstract
A syringe assembly includes a syringe and a tamper evident cap disposed over a Luer connection of the syringe, the tamper evident cap having a main body that defines a proximal end defining an opening, a distal end opposite the proximal end along the axial direction, an outer surface, and an inner surface opposite the outer surface that defines a passage to receive a tip cap and the Luer connection, where the tamper evident cap is spaced from the tip cap. The main body further defines a frangible connection between the proximal and distal ends of the main body. The frangible connection can break under a force applied to the distal end of the tamper evident cap such that the proximal end of the tamper evident cap remains engaged with the syringe when the frangible connection breaks.
