Patent ID: 8584796

Claim:
A tensioner for a safety line cable comprising: a fixing element coupled to a first end of the tensioner for fixing the tensioner to an external element; a sleeve coupled proximate a second end of the tensioner for crimping a section of the safety line cable proximate the second end of the tensioner, the sleeve having a hole for passing the safety line cable through the sleeve; a case having an opening, the opening in the case configured and arranged to allow an end of the safety line cable to pass through the sleeve and out of the opening of the case to allow access to the end of the safety line cable so a tension can be applied to the end of the safety line cable when the safety line cable is crimped in the sleeve; and a first section, the sleeve directly coupled to the first section; a second section, the fixing element directly coupled to the second section; and a fastener configured and arranged to selectively release the first section from the second section as a direct result of a predetermined pulling apart force threshold encountered between the first section and the second section; wherein the fastener further comprises: a threaded rod coupled to the first section; and a fuse nut threadably engaging the threaded rod, the fuse nut formed of material that is less hard than a material of the threaded rod to allow the release of the two sections after said force threshold is reached.
