Abstract: A modular storage system is described for storing and/or shielding a hypodermic needle which includes a modular needle container element for storing and/or shielding a hypodermic needles. The system includes a compartment for storing the needle, defined by first and second walls configured to be end walls, and a front wall and a rear wall extending between the first and second walls; each of the first and second walls has an outer surface directed away from the compartment, and each of the first and second walls include either a male connector on the outer surface of the wall or a female connector extending through the wall. The male connector includes a clip arm and the female connector includes a slot, such that the male connector is configured for engagement in a snap-fit manner to the female connector in the first or second wall of a second container element.
