Abstract
Abstract A connector joins a fish line to a leader without the need of knotting the fish line. The fish line is passed through a cylindrical opening located at one end of a round shaft, then wound around several spiral grooves in the surface of the shaft, then passed through at least two lock holes which are approximately perpendicular to the cylindrical opening and are recessed so that the fish line does not protrude out when passing from one lock hole to another lock hole. A leader is secured to a leader opening at the other end of the shaft. A soft plastic tubing may be inserted into the cylindrical opening to prevent the weakening of the fish line while trolling.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
76 words
A knotless fish line connector comprising a shaft with a cylindrical opening at one end and a leader opening at the other end, at the end of the cylindrical opening are spiral grooves in the surface of the shaft, at the end of the last spiral groove is at least one locking groove in the surface of the shaft, at the end of the last locking groove are at least two locking holes in the shaft.
Claim 2
Dependent Claim
76 words
A knotless fish line connector comprising a shaft with a cylindrical opening at one end and a leader opening at the other end, at the end of the cylindrical opening are spiral grooves in the surface of the shaft, at the end of the last spiral groove is at least one locking groove in the surface of the shaft, at the end of the last locking groove are at least two locking holes in the shaft.
Claim 3
Dependent Claim
55 words
The knotless fish line connector of claim 1, wherein the spiral grooves are curved at different angles in increasing amounts, with the spiral groove adjacent to the cylindrical opening being curved at the smallest angle and the locking groove is curved at an angle which is greater than the largest angle of the spiral groove.
Claim 4
Dependent Claim
22 words
The knotless fish line connector of claim 2, wherein there are at least three spiral grooves and at least three locking grooves.
Claim 5
Dependent Claim
19 words
The knotless fish line connector of claim 2, wherein cylindrical opening extends longitudinally within the shaft at an angle.
Claim 6
Dependent Claim
36 words
The knotless fish line connector of claim 2, wherein the locking holes are recessed at one end so that a fish line will not protrude out when passing from one locking hole to another locking hole.
Claim 7
Dependent Claim
37 words
The knotless fish line connector of claim 1, wherein the spiral grooves and the locking grooves are curved at the same angle and there are a minimum of five grooves, at least of which are spiral grooves.
Claim 8
Dependent Claim
29 words
The knotless fish line connector of claim 2, wherein there is a plastic tube within the cylindrical opening, which acts to prevent wear on a fish line when trolling.
Claim 9
Dependent Claim
43 words
The knotless fish line connector of claim 1, wherein there are three spiral grooves, one locking groove, and three locking holes, the locking holes are recessed at one end and there is a shank between the last locking hold and the leader opening.
Claim 10
Dependent Claim
42 words
The knotless fish line connector of claim 1, wherein the leader opening includes a cylindrical opening, spiral grooves, locking grooves, and locking holes, which are identical to those claimed in claim 1 and wherein it is joined thereto at a weight hole.
Claim 11
Dependent Claim
41 words
The knotless fish line connector of claim 9, wherein there are three spiral grooves, one locking groove, and three locking holes, the locking holes are recessed at one end and the cylindrical opening extends longitudinally within the shaft at an angle.
