A method for attaching a portion of an accessory to a wall of a vessel made of plastic, including shaping a parison by blowing. The accessory portion includes an attachment base including an open cavity including an opening leading to outside of the accessory portion, the open cavity including a female engagement shape shaped such that a male engagement shape complementary to the female engagement shape cannot, once engaged in the female engagement shape, be separated therefrom except by deformation or destruction of at least one of the engagement shapes. The method includes shaping a portion of the parison that is in a molten state, by molding same inside the cavity by a pressure difference established on either side of the portion of the parison, until the portion of the parison has a male engagement shape complementary to the female engagement shape formed by the open cavity.
