Assembly of a wristband to a watch case

A fixing device for fixing a wristband to a watch middle, comprising:

• a connecting element adapted for connection to one of the wristband or the watch middle,
• at least one pin able to occupy a first position projecting from the connecting element and a second position retracted into a housing of the connecting element,
• a receiving element adapted for connection to the other of the watch middle or the wristband, the receiving element comprising at least one bore, and
• at least one insert,
• the fixing device being designed to occupy at least a first configuration and a second configuration, wherein:
• in the first configuration, the at least one pin occupies a position retracted into the connecting element, enabling the wristband to be separated from the watch middle, and
• in the second configuration, the at least one pin occupies a position projecting from the connecting element and is positioned in the at least one bore of the receiving element, the at least one insert forming an interface between the at least one pin and the at least one bore and/or the housing to minimize frictional wear on rotation of the at least one pin relative to the receiving element and/or to the connecting element, respectively,
• wherein, in the first configuration of the fixing device, the at least one pin is free to rotate relative to the connecting element, and in the second configuration of the fixing device, the at least one pin is immobilized in rotation relative to the connecting element or relative to the receiving element.
