A two-piece cable tie is provided that can be more readily assembled and achieves a low insertion force while maintaining desired strap retention force. The cable tie includes a metal locking device that is bent at a predetermined bend angle and then precisely located within a locking device receiving cavity. The cable tie includes a strap including a first end and a free end and a locking head secured to the first end of the strap along a strap attachment axis. The locking head includes a strap accepting channel in the head that has a strap entry end and a strap exit end on opposite ends of a strap accepting channel axis. The strap accepting channel divides the locking head into a first part and a second part, with the first part being secured to the first end of the strap and the second part including metal locking device receiving cavity adjacent to and open toward the strap exit end of the locking head and an extending wall located between the receiving cavity and the strap accepting channel. The metal locking device, which is preferably prebent, is mounted within the metal locking device receiving cavity by having a fixed end mounted to a support slot of the end wall of the locking head and oriented substantially parallel to the strap accepting channel axis. The metal locking device further includes a free end angled at an acute angle relative to the strap accepting channel axis and extending into the strap accepting channel. When mounted, the free end preferably substantially rests upon a fulcrum point of the extending wall and extends beyond the wall by a predetermined distance into the strap accepting channel.
