Abstract: A choke collar for pets includes a stranded wire cable core having free ends each of which is given an enlarged head. A sheath of synthetic plastics material encloses the core substantially its entire length between the beads and is preferably impregnated with a pesticidal composition. First and second cooperable locking elements connect the free ends of the collar and provide for adjustment of the collar diameter, and a lock sleeve is slidably mounted on the sheath and is dimensioned to be positionable over the first and second locking elements to present a smooth external surface. A snap ring is slidable on the sheath to receive a leash.
