Connector, releasable cambium saver provided with one such connector and method for use thereof

A connector comprising:

• a first ring fitted openable and provided with a blocker collaborating with a rod, the rod being fitted movable between a first position of the rod where the first ring is closed and a second position of the rod where the first ring is open, the blocker being fitted movable between a first position of the blocker collaborating with the rod in the first position of the rod to keep the first ring closed and a second position of the blocker allowing opening of the first ring;
• a second ring distinct from the first ring and designed to receive a wire part, the second ring having a variable cross-section, the cross-section varying on account of a position of a probe, the probe being fitted movable with respect to a sliding area of the second ring to measure a thickness of the wire part running between the sliding area and the probe;
• wherein the probe is connected to the blocker so that when the distance between the probe and the sliding area is greater than a threshold value, the probe keeps the blocker in the first position of the blocker, and when the distance between the probe and the sliding area is lower than a threshold value, the probe allows movement of the blocker to the second position of the blocker.
