A coupling mechanism for connecting a replaceable shaving cartridge of a shaving device to a handle of the shaving device includes a first connector, a second connector, and a locking member. The first connector of the replaceable shaving cartridge is adapted to move along an axial direction. The second connector of the handle is adapted to move along a substantially arc-shaped path with respect to the handle when at least one connector of the first connector and the second connector is pushed against the other connector. The second connector is adapted to mechanically engage with the first connector in the course of its motion so as to reach an engaged position with the first connector. The locking member of the handle is adapted to lock the second connector when the latter is in the engaged position with the first connector.
