A retaining unit for retaining a container, comprising a supporting body, at least one gripping element and a resting element, the at least one gripping element and the resting element being mounted on the supporting body, wherein:

• the supporting body is configured to be mounted, in use, on a movement unit configured for moving the retaining unit along a movement path;
• the at least one gripping element comprises a first arm and a second arm, the first arm comprising a first gripping portion and the second arm comprising a second gripping portion, the first gripping portion and the second gripping portion delimiting between them, in part, a housing in which, in use, said container can be received;
• at least the first arm is mounted on the supporting body and is movable relative to the supporting body and to the second arm between a first returned position and a first opened wide position, the movement of the first arm from the first returned position to the first opened wide position causing a widening of the housing;
• the resting element has at least one resting portion which also partly delimits the housing and which is configured to make contact, in use, with a lateral surface of the container;
• the housing has a main line of extension which is positioned vertically when, in use, the supporting body is mounted on the movement unit;
• the resting element is rotatably mounted on the supporting body according to an axis of oscillation transversal to the main line of extension of the housing, and can oscillate relative to the supporting body and to the first arm and the second arm around the axis of oscillation between a plurality of operating positions at each of which the resting portion is positioned differently and delimits the housing differently;
• the resting element has two resting portions spaced apart along a line perpendicular to the axis of oscillation, the two resting portions being configured to make contact, in use, with different parts of the lateral surface of the container;
• and
• at each operating position corresponds a different position of the two resting portions relative to the supporting body.
