An inline fuse holder assembly encloses a fuse assembly including a fuse, and first and second wire connectors at respective first and second longitudinal ends of the fuse assembly. The inline fuse holder assembly includes first and second components including respective first and second connectors. The first and second connectors include mateable, non-releasable connection components configured to connect the first and second components to one another and form a substantially waterproof, non-releasable connection upon connection. The first and second components together define an enclosure for enclosing an entirety of the fuse assembly when the first and second fuse holder components are connected to one another.
