Locking device and method for fixation of components to tubes

A locking device adapted for fixation to an elongated element, the locking device comprising a first and a second lock housing, wherein each lock housing comprises:

• a first side having a hole positioned on the first side and adapted to receive a screw;
• and
• second and third sides perpendicular to the first side,
• wherein:
• the second and third sides each comprise a recess with an opening along its periphery, said recess being adapted to receive the elongated element;
• the second and third sides are opposite to each other and the recesses have substantially the same dimension and shape such that the elongated element is permitted to move through the lock housing,
• the second and third sides each comprises at least two through holes adapted to be connected to corresponding holes or protrusions on a lock plate, and
• a direction of the at least two through holes is perpendicular to a direction of the hole positioned on the first side,
• wherein the first lock housing is configured to be assembled with the second lock housing such that the openings along the periphery of the recesses of the second and third side of the first lock housing are placed opposite to the opening along the periphery of the recesses of the second and third side of the second lock housing to form a geometry,
• wherein said geometry, once assembled, comprises through holes formed by the recesses in the first and second lock housings,
• wherein said through holes correspond to a geometry of the elongated element, and
• wherein the hole positioned on the first side is positioned such that a screw placeable in said hole can engage the elongated element when placed in the through holes formed by the recesses, and
• wherein the locking device further comprises a first and second lock plate, each lock plate comprising at least two features for connecting the first and second lock housings, wherein each feature comprises at least one of a hole and a protrusion.
