1. A device for a first steel tube designed to be secured on a portion of said tube used in a tubular column for oil & gas, energy, or storage applications, said device comprising:
a substantially cylindrical envelope extending along a longitudinal axis and designed to surround the portion of the first steel tube, said envelope forming an open ring so that a circumferential gap subsists between two free ends of said envelope; and
a locking lever fixed to the envelope in the vicinity of the circumferential gap and configured to clamp at least one cable while bringing the free ends of the envelope closer to each other in a locked position,
wherein the locking lever is pivotably mounted on the envelope and configured to rotate between an unlocked position in which said locking lever is radially away from the envelope and the locked position, and
wherein the inner surface of the locking lever of the locking lever includes a plurality of teeth configured to grip the at least one cable.
