A mould and method for the injection-moulding of an assembly for creating a closable fluid connection, and an assembly. The assembly comprises a female element (20) and a stopper (30) which is used to close off a bore (27) in the female element (20). The mould comprises a core with a core (2) with a core body (3) and a head (4). Furthermore, the mould comprises a mould ring which is composed of a plurality of mould parts (10, 11) are designed in such a manner that the mould cavity for the stopper (30), is located at a distance from the mould cavity for the female element (20). The mould parts (10, 11) of the mould ring which lie around the core (2) together delimit an annular sealing surface (15), by means of which the mould ring, in a zone between the mould cavity for the stopper (30) and the mould cavity for the female element (20), bears in a sealing manner against the core (2) during the injection moulding, so that the mould cavities are completely separated from one another.
An assembly for creating a closable fluid connection to be used in combination with a male element, which assembly comprises a female element and a stopper, the female element having a body with a bore which extends through the body and with a seat, which extends around the bore, for the stopper, which stopper is located in the seat and is used to close off the bore, the stopper having a side which faces the female element and a circumference, the stopper being provided on the side which faces the female element and distributed around the circumference with first hook members each having only an outwardly directed hook surface and second hook members each having only an inwardly directed hook surface, the bore of the female element forming a shoulder, behind which the outwardly directed hook surfaces of said first hook members engage when the stopper is in its seat, and the inwardly directed hook surfaces of said second hook members being engageable on a shoulder of a male element which is to be fitted into the bore of the female element.
