Cable tie

Abstract

A cable tie ( 100 ) comprising: a cord ( 101 ) having a first end ( 202 ) and a second end ( 103 ), and a locking head ( 104 ) fixedly attached to the first end ( 102 ), said locking head ( 104 ) being adapted to receive the second end ( 103 ) and retain the cable tie ( 100 ) in a closed loop configuration, wherein the locking head ( 104 ) defines (a) wall(s) ( 105 ) that encircles a passage ( 106 ) having an inlet ( 107 ) and an outlet ( 108 ), and comprises a protrusion ( 109 ) that extends into the passage ( 106 ) for engaging the cord ( 101 ) and which is arranged to allow displacement of the cord ( 101 ) in a first direction towards the outlet ( 108 ) while preventing displacement of the cord ( 101 ) in a second direction towards the inlet ( 107 ), and wherein the cord ( 101 ) comprises a paper strip ( 10 ) twisted along its length, the number of turns per meter of the twisted paper strip being 55 - 75.
