An interface system for cabin trolleys for a vehicle, comprising:

• a first interface device attachable to a monument inside a cabin;
• a second interface device attachable to a cabin trolley;
• wherein the first interface device comprises at least one of a first electrical port, and a first water port;
• wherein the first interface device comprises a first guide element and at least one first locking element;
• wherein the second interface device comprises at least one of a second electrical port, and a second water port;
• wherein the second interface device comprises a second guide element and at least one second locking element;
• wherein the first interface device and the second interface device are configured complementary to each other, such that the at least one of a first electrical port, and a first water port, and the at least one of a second electrical port, and a second water port connect to each other in a connecting position;
• wherein the first guide element and the second guide element are configured to engage with each other to guide the first interface device and the second interface device into the connecting position;
• wherein the first locking element and the second locking element are configured to releasably lock each other to arrest the first interface device and the second interface device in the connecting position,
• wherein the second interface device comprises at least one cover flap, that is swivably mountable on the trolley and is positionable into a closed and an opened position, and
• wherein the at least one cover flap covers the second interface device in the closed position.
