Abstract

A coupling for a medical instrument for connecting two lines, with a first coupling part, and with a second coupling part which can be inserted into the first coupling part in the longitudinal direction of the coupling parts. The coupling comprises first locking elements arranged on the first coupling part and second locking elements arranged on the second coupling part, the first locking elements being movable between a locking position, in which they engage with the second locking elements, and an unlocking position, in which they disengage from the second locking elements. The coupling further comprises retaining elements which are arranged on the first coupling part and which are movable between a retention position, in which they keep the first and second locking elements in engagement with each other, and a release position, in which the first and second locking elements can be disengaged. It is proposed that the first coupling part comprises a slide which is movable in the longitudinal direction thereof and which, upon insertion of the second coupling part into the first coupling part, is moved from an advanced position to a recessed position, that the slide is biased into the advanced position, and that sealing elements are arranged on an end of the second coupling part directed towards the first coupling part which in a state in which the first coupling part is connected to the second coupling part, seal off an interior of the coupling with respect to a fluid.
