Tension release coupling for fishing line

Claim 1

A tension release coupling assembly adaptable for a fishing line having a cord and a fishhook assembly, and comprising a resilient coupling member attachable to the cord and a connector member which is part of the fishhook assembly and releasably coupling with the coupling member, said coupling member consisting of a one piece body of resilient plastic and non compressible material, said body being elongated, having opposite sides and two opposite ends, and having a slot extending longitudinally thereof from one end towards but short of the other end, said slot opening at said opposite sides and at said one end and defining two elongated arms spaced from each other and integrally interconnected by a transverse bight portion at said other end, said transverse bight portion having a hole made therethrough for connection to said cord, said arms tapering in the direction of their free ends, having substantially flat internal surfaces facing each other and defining the side surfaces of such slot, each internal surface having a depression therein, the two depressions being in register transversely of the body, said depressions cooperatively forming a cavity with said slot, the free outer ends of said arms being each provided with a guiding notch extending at least partially in said internal surfaces, the two guiding notches being in register with each other transversely of the body and with said depressions longitudinally of the body, said connector member including an enlarged head removably insertable into said slot by movement along the longitudinal axis of said body by being guided by said guiding notches upon engagement therewith, said movement continuing until said head fully engages said depressions, said head having an external surface, complementary to said cavity.
