This invention provides a cable tie (10) having a head (14) formed with at least two capturing slots (15, 25) and associated pawl mechanisms (16'/26') one of which is selectively releasable by actuation of a finger tab (31) which projects from the head (14) which may be pivoted to causing the pawl (26) in the releasable pawl mechanism (26') to move in the capturing slot (25) from locking engagement with the tail (11) of the tie (10) to a disengaged position at which the tail (11) may be moved freely through the slot (25) unimpeded by the pawl mechanism (26').
