Abstract: A device and method for securing a tether, such as a lead rope used to tie a horse, to a fixed object, such as a tie-rail. The load end of the tether, which is attached to the horse's halter, is looped one or more times over the tie-rail, and the invention secures the loose end of the tether to the load end of the tether. Adjustment of the device and method determines the tension or load at which the horse can pull out additional rope. The device can be easily applied and removed. Pulling down on the loose end of the lead rope releases the device quickly when needed.
