Abstract: A generally tubular textile braid is divided into two axially extending portions by stitching or otherwise securing opposed wall portions of said braid together, one of said portions being adapted to receive a wiring harness and the other containing an axially extending reinforcement constituted by a second tubular braid of the same or a different textile material, the two braids being formed with the same or very similar braiding angles, so that on radial expansion of the first portion to install it over a substrate such as a wiring harness assembly, both axially extending portions and the reinforcement contract by substantially the same amount in an axial direction.
