Not a knot connector is a great tackle for connecting the monofilament or braided line with a montage (a swivel, a hook, a jig or a snap ring) without a knot. Thanks to its unique as its part resembles a hook you thread into a chosen item of tackle, you hook a loop and turn round 5 times around the connector´s body and thread the end where the line clicks in. Afterwards you fasten it tightly and you get really tight connection without a knot that may reduce the loading capacity of the line.
