Abstract: A fishing line brake is mounted as a single unit on a rod and includes a main body and a pair of clamping arms that are rotatable relative to the main body. At least one guide ring is securely attached to at least one of the clamping arms. An actuation arrangement switches the line brake between a free-running configuration, in which the fishing line extends without contact through each guide ring, and a locking configuration, in which the lime is clamped between the clamping arms. At least one spring biases the brake into the free-running configuration. In a twin-ring embodiment two guide rings are attached to a different clamping arm. In a split-ring embodiment, a single guide ring is divided into two halves. Each half is attached to a different one of the clamping arms and forms a respective, separate closed loop. The loops formed by the guide ring halves extend through one another to form a closed ring.
