Abstract:
1. A crosspiece, comprising: a first part having a first terminal surface and a first edge distal to the first terminal surface; a second part having a second terminal surface and a second edge distal to the second terminal surface; a hollow bore formed from the first and second parts, the hollow bore having a longitudinal axis that is essentially perpendicular to the first and second terminal surfaces; and a clamp to keep the two parts assembled, wherein the first and second edges can be flattened against each other with the first and second edges having shapes that immobilize the first and second parts in a direction of the longitudinal axis so as to adjust the relative position of the first and second parts in such a way as to obtain a desired length between the first and second terminal surfaces, and the crosspiece can occupy only two states, a first unassembled state in which the first and second parts can be relative to one another along the longitudinal axis, and a second assembled state in which the first and second parts are immobilized relative to one another.
