Abstract
A safety elastic rope includes an elastic outer tubular rope having two longitudinally opposite first fixing ends, and an elastic inner rope inserted into the outer tubular rope and having two longitudinally opposite second fixing ends. The inner rope is more elastic than the outer tubular rope, and has substantially the same length as the outer tubular rope. The second fixing ends are connected respectively to the first fixing ends.

A safety elastic rope comprising:
- an elastic outer tubular rope having two longitudinally opposite first fixing ends;
- an elastic inner rope inserted into said outer tubular rope and having two longitudinally opposite second fixing ends;
- and
- two fixing members each of which connects one of said first ends to one of said second fixing ends;
- wherein said inner rope is more elastic than said outer tubular rope, said second fixing ends being connected respectively to said first fixing ends;
