A cable tie (10) comprises a head (12) and a strap (11). The head (12) has a transverse aperture (13) therethrough and a barb (25) formed separately from the head. The barb (25) has a head engaging portion (28), a strap engaging portion (27) and a region of flexure therebetween formed by a pair of opposed cut-out portions (30,31) to produce a section of reduced barb width. The barb can flex in a first direction to allow the strap (11) to be inserted in the head (12) but not in a second direction opposite to the first direction. Each cut-out portion (30,31) provides a shoulder at the side remote from the barb free end such that after the barb (25) is inserted into the head (12), material of the head flows over the shoulders to anchor the barb (25) in the head (12). <IMAGE> |
