To provide a two-piece cable tie which maintains strap retention force, can be readily assembled and achieves low insertion force.

The cable tie includes a metal locking device 136 which is bent at a predetermined angle and then precisely located within a receiving cavity of the locking device 136. It includes a strap 104 having a first end and a free end 138, and a locking head 102 secured to the first end of the strap along a strap attachment axis. The locking head includes a strap entry end and a strap exit end at both ends of an axis of a strap accepting channel 122. It includes the receiving cavity 180 of the metal locking device and an extending wall 142 located between the cavity and the strap accepting channel. A fixed end 134 is mounted on a support slot of an end wall of the locking head and oriented substantially parallel to an axis of the strap accepting channel. The metal locking device includes a free end angled at an acute angle relative to the strap accepting channel axis and extending into the channel and extends into the strap accepting channel.
