A clamping device comprising: a clamp frame that is configured to move between an open configuration, in which the clamp frame is configured to receive at least one longitudinal element, and a closed configuration, in which the clamp frame wraps around and holds the at least one longitudinal element, the clamp frame including a coupling end having an inner surface and a coupling base having an outer surface, the inner and outer surfaces having profiles adapted to form a locked engagement to hold the clamp frame in the closed configuration; and a secondary locking mechanism adapted to secure the coupling end and the coupling base to each other, the secondary locking mechanism being activatable after the clamp frame is held in the closed configuration by the locked engagement, and wherein the clamp frame has a passage through the coupling end and the coupling base has a base cavity that aligns with the passage when the clamp frame is in the closed configuration, the secondary locking mechanism including a locking pin having a handle and a pin segment extending through the passage and into the base cavity, the pin segment being rotatable about a pin axis, the base cavity being defined by a base surface of the coupling base, characterized in that the pin segment has a distal lobe that projects radially away from the pin axis, wherein the distal lobe is operable to engage the base surface and is configured to dislodge the coupling end from the coupling base as the pin segment is rotated about the pin axis to an unlocking position, wherein the distal lobe is configured to engage the base surface of the base cavity to urge the coupling end toward the coupling base as the locking pin is rotated about the pin axis to a locked position, wherein the base surface is configured to block the distal lobe from exiting the base cavity when the locking pin is in the locked position, the locking pin operable to be rotated to a neutral position between the locked position and the unlocking position, the base surface being configured to permit the distal lobe to exit the base cavity when the locking pin is in the neutral position, and wherein the coupling end is configured to block the distal lobe from moving through the passage when the handle is in the neutral position. a clamp frame that is configured to move between an open configuration, in which the clamp frame is configured to receive at least one longitudinal element, and a closed configuration, in which the clamp frame wraps around and holds the at least one longitudinal element, the clamp frame including a coupling end having an inner surface and a coupling base having an outer surface, the inner and outer surfaces having profiles adapted to form a locked engagement to hold the clamp frame in the closed configuration; and a secondary locking mechanism adapted to secure the coupling end and the coupling base to each other, the secondary locking mechanism being activatable after the clamp frame is held in the closed configuration by the locked engagement, and wherein the clamp frame has a passage through the coupling end and the coupling base has a base cavity that aligns with the passage when the clamp frame is in the closed configuration, the secondary locking mechanism including a locking pin having a handle and a pin segment extending through the passage and into the base cavity, the pin segment being rotatable about a pin axis, the base cavity being defined by a base surface of the coupling base, characterized in that the pin segment has a distal lobe that projects radially away from the pin axis, wherein the distal lobe is operable to engage the base surface and is configured to dislodge the coupling end from the coupling base as the pin segment is rotated about the pin axis to an unlocking position, wherein the distal lobe is configured to engage the base surface of the base cavity to urge the coupling end toward the coupling base as the locking pin is rotated about the pin axis to a locked position, wherein the base surface is configured to block the distal lobe from exiting the base cavity when the locking pin is in the locked position, the locking pin operable to be rotated to a neutral position between the locked position and the unlocking position, the base surface being configured to permit the distal lobe to exit the base cavity when the locking pin is in the neutral position, and wherein the coupling end is configured to block the distal lobe from moving through the passage when the handle is in the neutral position.
