A line clip 10 comprising a housing 12 defining a slot 16 for receiving a fishing line (fig 2, 40) and having three regions (fig 2, I, II, III) along the depth of the slot 16. The first region I is a gate to allow the line to pass in or out, if sufficient force is applied to the line parallel to the depth of the slot. The second region II is a free running region where the fishing line is trapped by the gate but can slide relative to the housing 12. The third region III is a clamping region where the fishing line is gripped in such a manner that it is prevented from sliding relative to the housing 12. In the third region, the line is gripped between two bodies (fig 2, 20 and 22) that are magnetically attracted to one another. The gate may be formed by two balls 30, 32 which may be made of a ferromagnetic material and the other is a permanent magnet, or they may both be magnets themselves. The balls and two gripping bodies, may be separate (fig 4) or integrally formed (fig 5). The gripping bodies may be cylindrical.
