Abstract: A fixing device for securing an elongate article such as a conduit to a support structure such as a wall of a cableway or cable riser, includes a housing provided with opposed hooks for securing the housing to the support structure by relative movement and then locking in place of the hooks. After the housing is mounted, the elongate article can be received in a U-shaped jaw provided on the housing, and a ratchet arm pivoted and latched to the housing, around the elongate article, trapping the elongate article in the jaw. Freeing the elongate article and dismounting the fixing device involve a reversal of these steps.
