Our Biothane® multi-purpose coupler is designed to be used in a variety of situations. Shorter lengths can be used to couple your dog's collar to their harness. Medium lengths can be used as a coupler or to secure your dog in the car. All you need to do is buckle your seat belt like normal, and then clip one end of your coupler around the strap and to the o-ring. The other clip is then secured to your dog's harness. Longer length couplers can also be used as a free-floating leash splitter. Since the o-ring is not secured in one location, we recommend this only for dogs who don't pull or lunge.
Couplers are made using 3/4" Beta BioThane and solid brass hardware.
