Abstract
The combination of a) a first tubular element with a first axis, a first portion with a radially outwardly facing surface and a first connecting assembly with a first circumferentially facing surface and b) a second tubular element with a second portion with a second axis, a radially inwardly facing surface, and a second connecting assembly with a second circumferentially facing surface. The first portion is extendable within the second portion. The first and second tubular elements are movable around the first and second axes between a) a first relative rotational position and b) a second relative rotational position such that the first and second connecting assemblies cooperate to draw the first and second portions axially towards each other and the first and second circumferentially facing surfaces confront each other to thereby block relative movement back into the first relative rotational position.
