The above figure shows the most common fuse arrangement in which the fuse wire is stretched between the two metallic terminals and in a porcelain holder.This holder fits into a porcelain socket having two metallic terminals to each of which the live wire of the circuit is connected.
A fuse must not be replaced with a copper wire because copper  has very low resistivity and high melting point. So it will not melt quickly because it will not produce much heat as compared to fuse wire.
