Patent ID: 7651138

Claim:
A coupling for a fluid conducting system, the coupling comprising: a coupling part into which an insertion section of a counterpart can be inserted, and a locking part mounted in movable fashion on the coupling part, the locking part having a detent structure which in a detent position interacts with a complementary structure configured on the insertion section for locking the counterpart and the coupling part, the locking part ( 20 ) being configured with two side sections ( 22 , 23 ) that are parallel to each other, each of the two side sections ( 22 , 23 ) having at least one longitudinal detent element ( 24 , 25 ) on the side sections' ( 22 , 23 ) insides facing the coupling part ( 1 ), and a latching structure ( 26 ) at the free end of the side section ( 22 ) and a latching structure ( 27 ) at the free end of the side section ( 23 ), the coupling part ( 1 ) being configured with guide recesses ( 13 ) that lie opposite each other and into which the detent elements ( 24 , 25 ) engage, the coupling part ( 1 ) is equipped in the region of one end of the guide recesses ( 13 ) with a latching structure ( 16 , 17 ), the latching structure ( 16 ) being configured complementary to the latching structure ( 26 ) on the side section ( 22 ), the latching structure ( 17 ) being configured complementary to the latching structure ( 27 ) on the side section ( 23 ).
