The system is attached or connectible to said vessel and comprises a first member, in which a puncturing member, e.g. a needle provided with a passage is enclosed the first member has a sealing member, e.g., a membrane through which the needle can be passed. The system further comprises a second member, which is detachably connectible to the first member and which also has a sealing member, e.g., a membrane.
