Lock arrangement and lock device

A lock arrangement comprising:

• an operating element including an engageable feature and arranged to be manually operated to rotate around a rotation axis between a closed position and an open position;
• a blocking element arranged to adopt a blocked position, in which the blocking element engages the engageable feature and thereby prevents the operating element from being rotated from the closed position to the open position, and an unblocked position, in which the blocking element does not engage the engageable feature and thereby allows the operating element to be rotated from the closed position to the open position;
• a control element rotatable around a control axis between a locked position and an unlocked position;
• and
• an intermediate element rotatably connected to the control element at a first pivot parallel with the control axis, and rotatably connected to the blocking element at a second pivot parallel with the control axis, the intermediate element being arranged to transmit a movement of the control element from the locked position to the unlocked position to a movement of the blocking element from the blocked position to the unblocked position;
• wherein each of the blocking element, the control element, and the intermediate element is made of plastic .
