A coupling link (1) comprises a unitary body having a first main limb (2), a second main limb (3), and a third limb (4) which forms an open loop (6), one end of which extends between the first and second main limbs. Loading of ropes, slings or protection onto the coupling limnk (1) is simply a matter of temporarily deforming the rope or device and looping it over the third limb (4). The required unloading action is too complex for it to happen accidently. The three dimensional topology of the coupling link (1) eliminates the requirement for a spring biased gate and is therefore inherently safer than a conventional karabiner. In a preferred example, the first and second main limbs are joined to form a closed loop (5).
