Embodiments for an in-line fuse holder each include at least one housing and two mating pieces, which can snap-fit together and be held moveably together via a strap. Each embodiment houses at least one fuse, such as an automotive fuse. In one example, the fuse includes a first housing forming a first cavity, which is configured to house a first portion of the fuse. The first housing also includes a projection having sides that taper outwardly as the sides extend away from the first housing. The fuse holder also includes a second housing forming a second cavity, which is configured to house a second portion of the fuse. The second housing includes a channel having sides that taper outwardly as the sides extend into the second housing. The projection and channel snap-fit together in a water resistant relationship.
