<p>The elongation part (5) is adapted to an inner dimension of a rod-shaped rail of a support (1), along an external dimension of the part, so that the part is insertable into the rail to connect the support with another support. The part has two mounting holes (25, 26) transverse to a longitudinal direction, so that a connection part is fixed in the rail by bolt-like locking parts (20) that are connected to the rail via holes (22) and the mounting holes. Independent claims are also included for the following: (1) an extension part kit for a support with an extension part (2) a connection part set (3) a longitudinally-adjustable mounting head for a support.</p> |
