Abstract
A snap-hook comprises a roller rotatably mounted in a first curved area of a body and cooperating with a finger to prevent opening of the finger in all angular positions of the roller except for an unlocking position in which it enables opening of the finger. The locking roller is rotated by the attachment line. Traction on the line locks the snap-hook automatically. Unlocking is achieved by pivoting the snap-hook body relative to the line.
