An access device (2) for external connection of an external circuit or a fluid source to a patient for medical purposes, including mouths (7) of access channels (8) with connections that are connectable to the patient and being surrounded by a connecting surface (6) , and a guide with holding elements (5) which is open in its both ends for the co-operation with holding means (17) on a coupling device (3,4) . Portions (30) of the access channels (8), which are most adjacent to each other are formed with curves that are directed to each other so that the course of a transition channel (9) , which is arranged to be formed by the access device and a connected coupling device of the kind which is formed in order to directly interconnect said two mouths, has an inner curved portion in the area of the connecting surface. The invention also concerns a method for producing an access device, a coupling device and an access system.
