摘要： A locking system is disclosed comprising two elements connected mechanically together so as not to be able to move apart, as well as a cam mounted for rotation on the first of said elements and having a contact surface pressing against a bearing face carried by the second of said elements.According to the invention, said contact surface of said cam has at least approximately a profile in the form of a logarithmic spiral, whereas said bearing face is flat and said cam may rotate about a hub on the axis of which is located the origin of said logarithmic spiral, said hub being mounted for rotation on said first element about an off-centered axis of rotation opposite said contact surface of said cam. Resilient means are provided for rotating said cam in a first direction such that said contact surface moves towards said bearing face.
