  • Patent number: 5024402
    Abstract: An improved cord restraint device is disclosed characterized by use of an elongate strap formed of an elastomeric material such as rubber capable of being readily stretched. Three apertures are formed in the strap with a slot extending between a pair of the apertures located adjacent one end. In operation, the strap is positioned about one end of the cord by insertion of the end of the cord through the single aperture which maintains the strap permanently upon the cord. The cord may then be coiled about the appliance, and the strap may subsequently be stretched such that the elongate slot is inserted over the end of the appliance to maintain the cord wrapped thereabout. The cord can be immediately removed from the appliance merely by restretching the strap such that the slot can be subsequently removed from engagement with the end of the appliance.
