Joint element for cable ladder and a method for the mounting of the same

A method for joining first and second side profiles of first and second cable ladders, respectively, end-to-end with each other using a joint element, the side profiles having a hexagonal cross section, each side profile having a first longitudinal edge and a second longitudinal edge located opposite to the first longitudinal edge, the method comprising:

• positioning the first side profile and the second side profile against each other end-to-end to form a joint;
• positioning a gripping edge of the joint element over the first longitudinal edge of the first and second side profiles across the joint and across the two ends of the side profiles abutting against each other;
• and
• turning the joint element around the joint such that a locking edge of the joint element connects to the second longitudinal edge of the first and second side profiles,
• wherein a free end of at least one locking tab of the locking edge abuts against at least one second longitudinal edge, the at least one locking tab is spaced from an end of the locking edge, and
• wherein the cross section of the joint element corresponds to the cross section of the side profiles.
