An electrical connection point including a functional block that includes a functional faceplate and a rear electrical plug and including a base that includes a housing to receive the functional block in a plugged in position. To reduce the risk of accidental detachment of the functional block, while improving the removable character of its fixing, the electrical connection point includes a lock with a ring that surrounds the functional faceplate and is disposed so as to be accessible from the outside of the housing when the functional block is received in the housing, the ring being rotatable relative to the rear electrical plug between an unlocking position to place the lock in the unlocking configuration and a locking position to place the lock in the locking configuration when the functional block is in the plugged in position.
