A brewing device for the brewing of a capsule containing a beverage ingredient, the device including a main frame, a first capsule holding part, a second capsule holding part for at least partially holding the capsule mobile relative to the first capsule holding part in the frame and linked to the frame by a closing mechanism that includes knuckle joints; and a manual handle forming lever to activate via the closing mechanism the second holding part from the open position to the closed position and vice versa. The closing mechanism includes an additional force transmitting member associated with the handle and arranged to de-multiply the force applied by the handle on the knuckle joints that compensates for the increase of the force needed for closing the holding parts on the capsule.
