A pole section for temporary assembly with similar pole members into an pole assembly to extend the manual reach of a user whereby a user can perform work on a worksite remote from the user where the site is elevated by up to 20m above the user comprising: an elongate tubular pole section having a male end part and a female end part configured so that the male end part of a first pole section can fit a predetermined distance into a female end part of a second pole section to form a fluid tight sliding fit without obstructing the bore of the pole sections; each pole section having a first coupling part provided adjacent a female end of the pole section and a co-operable second coupling part provided at a predetermined distance from the male end of the pole section whereby the first coupling part of a first pole section will disengageably engage with the second coupling part of a second pole section when the respective male end is received into the female end in order to prevent unwanted relative longitudinal movement of the first and second pole sections ; wherein the outside surface of the male end is tapered and the internal surface of the female end of the pole section is tapered to provide a corresponding surface and each coupling part is provided by a collar secured to the external surfaces of the respective male end and female end of the pole section such that only a predetermined length of the pole section can be inserted into another pole section to prevent the pole sections jamming together, the first coupling part being engageable with the second coupling part by means of at least one pin projecting radially from one coupling part to engage in a track formed in the other coupling part, the track configured to require the coupling parts to go through a sequence of axial and circumferential movements to be coupled or uncoupled, and characterised in that a resilient structure is incorporated into at least one of the coupling parts to discourage unintentional movement and therefore to resist uncoupling, the resilient structure being located in the coupling parts so that the weight of another coupled pole section will not be applied to the resilient structure. an elongate tubular pole section having a male end part and a female end part configured so that the male end part of a first pole section can fit a predetermined distance into a female end part of a second pole section to form a fluid tight sliding fit without obstructing the bore of the pole sections; each pole section having a first coupling part provided adjacent a female end of the pole section and a co-operable second coupling part provided at a predetermined distance from the male end of the pole section whereby the first coupling part of a first pole section will disengageably engage with the second coupling part of a second pole section when the respective male end is received into the female end in order to prevent unwanted relative longitudinal movement of the first and second pole sections ; wherein the outside surface of the male end is tapered and the internal surface of the female end of the pole section is tapered to provide a corresponding surface and each coupling part is provided by a collar secured to the external surfaces of the respective male end and female end of the pole section such that only a predetermined length of the pole section can be inserted into another pole section to prevent the pole sections jamming together, the first coupling part being engageable with the second coupling part by means of at least one pin projecting radially from one coupling part to engage in a track formed in the other coupling part, the track configured to require the coupling parts to go through a sequence of axial and circumferential movements to be coupled or uncoupled, and <EOS>
