Abstract
The invention relates to an automatically-closing connector. The connector has a closing piston which is rigid and non-deformable; a compression chamber is constituted around the closing piston and is defined upstream by the end wall of the housing and downstream by a peripheral sealing gasket carried by the piston; the outlet of the connector is situated downstream from this gasket and the closing piston has an internal passage with an inlet that opens out into the compression chamber and an outlet that communicates with the outlet of the connector. The connector is applicable to injection devices in the medical field.
