A telescopic device comprising a first tubular element and an extension member displaceably arranged in an axial direction within the first tubular element, between at least, a first axial position wherein the extension member is displaceabie within the first tubular element, where the fiirst tubular element comprises a first coupling means and the extension member comprises a second coupling means, and in a second axial position where the first and second coupling means cooperate with each other for limiting the displacement of said extension member in at least one longitudinal direction, where the first and/or the second coupling means are provided with at least one protrusion in a radial direction of a longitudinal axis of the first tubular element and/or the extension member.
