Abstract
Disclosed herein is a retractable leash device in which the leash cable, which is wound on a spring-loaded spool, is threaded through the handgrip area of the casing before it exits the casing at an area remote from the handgrip. The handgrip is provided with a spring-loaded braking plate, so that squeezing the handgrip causes the teeth on the braking plate to engage and stop the leash cable. The leash cable can be freely payed out or retracted until the handgrip is squeezed by the operator, which stops the motion of the cable.
