A gun for applying cable ties includes a pinch wheel for acting on the flat tail of the tie to drive the tie from the gun, the tie being guided (as it is advanced, tail-first) around a nose loop guide. The tie finishes with its head engaged with a threader which is then lifted to lift the tie head and thus cause the tail to pass through the head aperture, become interlocked therein and project from the lower side of the head. Then the threader is lowered to lower the head and engage the projecting end of the tail with a pinch wheel which serves to tension the tie. The ties are fed from a bandolier of side-by-side ties in which they are interconnected at their heads and tail tips by continuous strips running along the edges of the bandolier, successive ties being cut from the bandolier while leaving the two strips intact.
