An improved cable or bundle tie arrangement includes a plastic tie strap and a tie head. The tie head includes a housing having a pair of spaced apart slots extending therein forming a pair of strap-receiving passageways. Each passageway has an entrance opening and at least one of the passageways has an exit opening. A pawl-receiving channel extends through the housing intermediate the passageways having at least one channel opening disposed substantially normal to the entrance openings. An intermediate portion of the channel intersects each of the passageways. A pawl member is mounted in the channel through the channel opening. The pawl includes a base portion and a pair of arms extending from opposed sides of the base. Each pawl arm has a free end with a blade section. The free ends of the pawl arms extend from the channel into the adjacent strap passageways for making biting and wedging engagement with an inserted tie strap to lockingly maintain the strap under tension around the article or bundle being tied.
