Abstract: A fishing bobber assembly. The assembly includes an elongated body having spaced end panels and an elongated bore. A radial slot in the body extends outwardly from the bore through an outer face of the body. The bobber assembly also includes plug members, each of which includes a stem frictionally receivable in the bore at one of the end panels and a head for bearing on said one of the end panels. An elongated bore in each plug member extends lengthwise of the stem and the head thereof. A radial slot extends from the bore of each plug member through an outer edge thereof. The slots of the plug members are alignable with the radial slot of the body so that a line can be inserted through the slots. The line is locked in the bores of the body and the plug members when the plug members are rotated from aligned position.
