Abstract
A coupling assembly adapted to connect a fishhook to the remainder of a fishing line, including the lure, and which responds to tension on this remainder of the fishing line to release the same free of the fishhook when the latter catches a submerged obstacle. This tension release coupling assembly includes a resilient coupling member, such as of plastic, which is attached to the cord of the fishing line and which has a cavity therein adapted to releasably catch the eye of a common fishhook or an enlarged end portion of a specially made fishhook or hook connector member. The resilient coupling member may be calibrated in relation to the different strengths of cord used for the fishing lines such that the fishhook will be released before the tensional strength of the corresponding cord is reached. The resilient coupling members are colored in accordance with a code distinctive of the predetermined calibration of strength thereof.
