A line attaching apparatus, system and method for attaching to a line end without the need for tying a knot. The invention further comprises a line attaching apparatus, system and method for attaching to a first line end portion to a second line end portion without the need for tying a knot. The line end portions may be captured in a collet having a line retention and a line insertion/removal state. The collet may be biased into a line retention state by a biasing force that causes the collet to close around a line, preventing the line from translating within the collet. The line insertion/removal state may be achieved by motivation of a plunger against the biasing force, allowing the collet to open so that a line moves freely within the collet opening. An exemplary, non-limiting use is the attachment of a lure or hook to a fishing line.
