<p>There is described ducting comprising a plurality of interconnectible elongate ducting components ( 2, 4 ) which when assembled define an elongate, longitudinally extending internal channel ( 22 ) for receiving a pipe, cable or like elongate member, each ducting component having a shaped inner face ( 14 ) with a longitudinal recess ( 20 ) such that the components can be assembled with confronting inner faces ( 16, 18 ), their respective longitudinal recesses being thereby aligned to form the channel, the ducting further comprising tension bands ( 6 ) for securing assembled pairs of components to one another, wherein each ducting component is provided with a transversely extending internal cavity for receiving a tension band, the cavity having two open ends so that the band can pass through the internal cavity of one ducting component and though a corresponding internal cavity of an adjacent ducting component in order to secure one to the other, at least part of the band being thereby contained and protected within the cavities.</p> |
