The elastic tubing stretches a first predetermined length. First and second end plugs are secured inside the elongated cavity at the respective first and second ends, with a widest portion of each first and second end plugs closest to its respective first and second ends. A cord has third and fourth ends that is threaded through the elastic tubing and the first and second end plugs. The cord is a second predetermined length that is shorter than the first predetermined length. ## Claims ### Claim 1 An elastic exercise safety cord assembly, comprising: A) an elastic tubing having opposing first and second ends, an exterior wall, and an elongated cavity having a first diameter, said elastic tubing stretches to a first predetermined length; B) first and second end plugs wider than said first diameter, said first and second end plugs each have a hollow core through an entire length of said first and second end plugs and are secured inside said elongated cavity at respective said first and second ends, with a widest portion of each said first and second end plugs closest to its respective said first and second ends; C) a cord having opposing third and fourth ends, said cord threaded through said elastic tubing and said first and second end plugs, said cord is a second predetermined length that is shorter than said first predetermined length, said cord comprises end knots at each of said third and fourth ends, said cord keeps said elastic tubing attached and confined when said elastic tubing breaks to prevent said elastic tubing from striking and/or causing damage to person and/or property; and D) first and second inserts being flexible to permit said cord to fit through said first and second inserts. ### Claim 2 (depends on 1) The elastic exercise safety cord assembly set forth in claim 1, further characterized in that said elastic tubing is configured to fit onto an attachment device that has a continuous channel going through an entire length, said continuous channel being of a sufficient diameter as to allow said elastic tubing to pass through it but not said first and second end plugs. ### Claim 3 (depends on 2) The elastic exercise safety cord assembly set forth in claim 2, further characterized in that said attachment device is a docking block. ### Claim 4 (depends on 3) The elastic exercise safety cord assembly set forth in claim 3, further characterized in that said docking block comprises a sidewall and fifth and sixth ends. ### Claim 5 (depends on 3) The elastic exercise safety cord assembly set forth in claim 3, further characterized in that said docking block further comprises a block cavity defined by said continuous channel. ### Claim 6 (depends on 3) The elastic exercise safety cord assembly set forth in claim 3, further characterized in that said docking block further comprises openings. ### Claim 7 (depends on 3) The elastic exercise safety cord assembly set forth in claim 3, further characterized in that said docking block further comprises at least one channel slit. ### Claim 8 (depends on 2) The elastic exercise safety cord assembly set forth in claim 2, further characterized in that said attachment device is a handle assembly. ### Claim 9 (depends on 8) The elastic exercise safety cord assembly set forth in claim 8, further characterized in that said handle assembly comprises a handle cavity defined by said continuous channel. ### Claim 10 (depends on 8) The elastic exercise safety cord assembly set forth in claim 8, further characterized in that said handle assembly comprises at least one handle slit. ### Claim 11 (depends on 1) The elastic exercise safety cord assembly set forth in claim 1, further characterized in that each of said first and second inserts comprise a sidewall, a hole, and an insert end. ### Claim 12 (depends on 11) The elastic exercise safety cord assembly set forth in claim 11, further characterized in that said sidewall comprises a slit. ### Claim 13 (depends on 1) The elastic exercise safety cord assembly set forth in claim 1, further characterized in that said end knots are secured by respective said first and second inserts. ### Claim 14 (depends on 13) The elastic exercise safety cord assembly set forth in claim 13, further characterized in that said first and second inserts are secured within respective said first and second end plugs. ### Claim 15 (depends on 1) The elastic exercise safety cord assembly set forth in claim 1, further characterized in that said first and second end plugs are tapered. ### Claim 16 (depends on 1) The elastic exercise safety cord assembly set forth in claim 1, further characterized in that each of said first and second end plugs comprise a sidewall and a plug end.
