Abstract
The invention relates to a male connector for a liquid circuit, comprising: a distal connection piece comprising a tubular part that defines a passage; a proximal connection piece; a joining member extending in a fixed and co-axial manner in the tubular part of the distal connection piece, the joining member being formed by a tubular body on which is fixed, at a free end, a cylindrical valve which is elastically deformable and closed at a distal end by a valve thickness traversed by a slit; and a sliding ring mounted on the tubular body, the sliding ring being movable between an inactive position, in which it encapsulates the walls of the valve, leaving the distal end of the valve free, and a connection position, in which it is situated at a distance from the distal end of the valve and exposes all or part of the lateral walls of the valve.
