A sliding buckle adjusts leash loop size for hand carry, shoulder carry, or tie-off while keeping the pet securely restrained.
A shelf structure blocks collar-loop contact with the tab, preventing accidental leash clip opening while keeping intentional release easy.
An elastic orientation member keeps the coupler perpendicular to the surface, enabling one-handed fastening and reducing contact hazards.
A spring-biased sliding sleeve and guided track help this coupling resist tensile-force opening while keeping attachment and release simple.
A pivoting, biased catch keeps dog leads secure under tension while allowing easy one-handed opening, even if the bias mechanism fails.
