A cable tie having an elongated tongue with two ends and two broad sides, a tip at one end of the tongue, a set of ratchet teeth extending along at least one broad side of the tongue, and a locking head at the other end of the tongue. The locking head has sides defining an opening for receiving the tip of the tongue, and a movable pawl that is hinged at one side of the opening, with another side of the locking head defining an abutment wall that is across the opening from the pawl. The pawl engages with one or more of the ratchet teeth when the tongue has been inserted through the opening with the set of ratchet teeth facing the pawl. At least one other side of the locking head defines a thinned region that can be torn by the user to release the tongue from the head.
