Abstract
The needle is formed pref. with reduced cross-section at its operative end, and this end has, either in the sides or across the end, one or more V-shaped grooves, having their open ends facing the needle end, to define barbs which do not extend beyond the maximum transverse dimension of the needle. The reduced section may be circular or triangular cross-section, and a spike may be provided extending axially from the needle end. The needle is resistant to breaking.
