Abstract
Abstract A device for suspending a cord such as an electric cord from a support to prevent straining and premature failure of the cord. The device consists of a flat elongate flexible member which is wrapped around the cord and secured thereto so as to prevent relative movement therebetween by means of a slot formed in one end thereof, which slot receives the other end of the member, with detent means formed in the member so that when the member is in enclosing supporting relationship with the cord, the detent means engages the portion of the member defining said slot to hold the member on the cord. The outer end portion of the end which is inserted in the slot is provided with an opening for connection to the cord supporting member.
