The long hose (3) is shortened by folding, so that it can be accommodated inside a holding ring (2), one end of it being fixed to the latter.The grip guard (6), on its side towards the sterile portion (4), is coaxial to the hose, and extends over the axial length of the ring, with which it can be integral. It can be formed by the folded-over hose end which is fixed to the ring. Before use, the guard can be folded flat round one ring end face and/or inside the ring. |
