Yes, we fit the cord as standard but please note it is not a restraint.  Designed if the cord is snagged/caught to pop out. The leash can be trapped under your wetsuit Velcro for added security.  Always check to see secure. Please note the cord is not designed to be repeatedly removed & refitted as this will damage the Surfplugs® If you prefer not to have a cord fitted then this may be removed by simply unscrewing the leash from the Surfplugs®,  This will leave a small hole which will not cause any problems but for cosmetic purposes we are happy to fill and seal the hole free of charge if you send the Surfplugs®,  back to us.
