ABSTRACT:
In a tree skidding arrangement comprising a mainline secured to the winch of a line skidder and having a number of chokers secured to sliders which are freely slidable along the mainline, the last choker is secured to the mainline through a cable coupler. The coupler is formed in two parts which can be screwed together and each of which has an orifice therethrough for respectively accommodating a mainline ferrule and a choker ferrule. At least the part accommodating the choker ferrule has a smoothly tapered or rounded nose portion, which minimizes the tendency of the coupler to snag on trees or bushes.
