A container for holding and protecting a fishing lure attached to the line of a fishing rod comprises a unitary envelope of rubber-like material. The envelope has an elongated rectangular body with pyramidal end regions. A normally closed slit in one face of the envelope extends from the apex of one end region to the apex of the other end region. When the ends of the container are squeezed toward each other, the slit opens providing a generally rectangular opening for the length of the container. An opening in the apex of one end region allows the line to pass out of the container. A hook on the container enables it to be attached to one of the line guide rings on the rod.
