ABSTRACT:
This invention relates to a leash which coils up automatically when the handle is released. The invention comprises a generally cylindrical center portion with handles on either side, which is manufactured in two parts and can be assembled easily. The two parts are then sonically sealed to provide a strong and secure body. A retractable spring is fixedly attached inside in such a manner that it easily pulls out and retracts without catching or snagging.
