Abstract: This clamping device includes a clamping collar intended to surround an element to be clamped and open so as to have two ends able to come closer to one another in order to grip the element to be clamped. This device also includes a lever, mounted tilting on the ends of the collar around a tilting axis perpendicular to a central axis of the collar, and connected to the collar by a cam system able to be actuated by tilting the lever. The cam system includes at least one pair associating a cam surface and a counter-cam surface, which are each globally helical and which are respectively connected in rotation to the collar and the lever.

Abstract: Cycle storage and locking system for locking plural cycles in at least one storage station. The system includes plural locking and storage points each structured and arranged to lock one of the cycles at the at least one storage station. Each of the plural locking and storage points comprises two arms and a space arranged therebetween sized and configured to receive therein a front wheel of one of the cycles. A locking arrangement is structured and arranged to lock one of the cycles to one of the plural locking and storage points. The locking arrangement includes two laterally movable lateral locking projections arranged on the one of the cycles and two locking recesses arranged on the one of the plural locking and storage points.

Abstract: The invention relates to a cycle storage and locking system, which includes a plurality of cycles (1) and at least one storage station including a plurality of storage and locking points, while the system includes means for locking each one of the cycles to one of the storage and locking points, each one of the storage points being made up of two arms, forming between them a space in which the front wheel of the cycle is intended to be inserted when positioning the cycle, while the means for locking each one at the cycles are made up of two laterally mobile side projections (6a, 6b) engaging with two locking recesses (7a, 7b), characterised in that the cycle includes the two mobile locking projections and the storage point includes the two concave locking recesses (7a, 7b).
