Abstract

The present invention relates to a self-closing coupling device 1;1';1" which comprises a rigid casing 4;4';4", members 7;7';7" for connecting the casing 4;4';4" in a sealing manner, to a hose or to a pipe, and also sealing members 2,3;2',3';2",3" made of flexible material which are affixed inside the casing. Coupling devices of the abovementioned type are intended to be used together with injection needles or the like, with injection needles penetrating the sealing member 2,3;2',3';2",3" and establishing a connection with the pipe or the hose which is connected to the coupling device 1;1';1". The invention is characterized by the fact that the sealing member consists of at least two grommets 2,3;2',3';2",3" which are arranged at some distance from each other in the axial direction of the casing 4;4';4". The grommets 2,3;2',3;2",3" expediently have a somewhat larger diameter than the diameter of the casing 4;4';4", for which reason a radial compression is applied to the grommets 2,3;2',3';2",3" when they are being installed in the casing 4;4';4". <IMAGE>
