A cable tie having a locking head and a strap terminating in a tip is formed by injecting plastic material into a mold cavity defined by a first mold part that includes a head region defining a portion of the head and a second mold part that includes a tip region defining a portion of the tip. Upon initial separation of the mold parts a portion of the head is retained in the head region of the first mold part and a portion of the tip is retained in the tip region of the second mold part. Upon further separation of the mold parts, the tip is still retained in the tip region of the second mold part and the head is removed from the head region of the first mold part. Subsequently, the tip of the cable tie is ejected from the tip region of the second mold part.
