Abstract
Abstract This is a rapid action connecting element for tubular fishing lines: This element can be used to repair cut lines and to assemble sections. The element comprises a single flexible pin with rounded ends with barbs at its ends having their point directed toward the central section of the pin. Half the pin is introduced into a hole in one tubular line and the other end of the pin is introduced into an end of another tubular line. Upon pushing the ends of the tubular lines together, they are held connected, by reason of the barbs becoming embedded in the lines.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
110 words
A rapid connector element for tubular fishing lines characterized by the fact that it comprises a single solid pin having rounded blunt ends, which has a smooth central section and two side sections contained between the limits of said central section and the respective ends of the pin, each provided with a set of protruding curved, painted barbs, which, acting as hooking fins, are inclined in such a manner that their sharp points are directed towards parallism with the central section of the pin, said pin being of uniform cross section except for said barbs, and having an outer cylindrical surface, and said barbs extending outwardly of said cylindrical surface.
