In the case of a fluidic nozzle (12) a nozzle body (13) is fixed in a housing (17) by a form-locking latching connection (18). For this purpose, an elastically deformable latching body (14) engages in a recess (16) of the housing (17). The operational position of the nozzle body (13) is thereby defined with high accuracy, with the result that an undesirable escape of the liquid between the nozzle body (13) and the housing (17) is prevented. Furthermore, at the same time the contact surface can be reduced here to a section (20) which is inclined toward an outlet opening (19) of the fluidic nozzle (12) and has a correspondingly improved sealing.

1. A fluidic nozzle comprising: a housing (1, 17) having an inlet opening for liquid, and a pocket (3); a nozzle body (4, 13) to be introduced from a front side (11) of the fluidic nozzle into said pocket (3); and a form-locking latching connection (8, 18) fixing said nozzle body in said housin
1. A fluidic nozzle comprising: a housing (1, 17) having an inlet opening for liquid, and a pocket (3); a nozzle body (4, 13) to be introduced from a front side (11) of the fluidic nozzle into said pocket (3); and a form-locking latching connection (8, 18) fixing said nozzle body in said housing, without deformation of said nozzle body and said housing, in an operational position, wherein the form-locking is attained by complementary forms of the nozzle body and the housing; wherein said latching connection (8, 18) is arranged on a fixing surface, and said fixing surface is arranged on a side of the nozzle body (4) which lies opposite an inlet opening (5). 2. The fluidic nozzle comprising: a housing (1, 17) having an inlet opening for liquid, and a Docket (3); a nozzle body (4, 13) to be introduced from a front side (11) of the fluidic nozzle into said pocket (3); and a form-locking latching connection (8, 18) fixing said nozzle body in said housing, without deformation of said nozzle body and said housing, in an operational position, wherein the form-locking is attained by complementary forms of the nozzle body and the housing; wherein the latching connection (8, 18) is formed by a recess (10, 16) and a projection (9, 15) engaging in the recess, and the recess (10, 16) is arranged on the nozzle body (4, 13) and the projection (9, 15) is arranged on the housing (1, 17). 3. A fluidic nozzle comprising: a housing (1, 17) having an inlet opening for liquid, and a pocket (3); a nozzle body (4, 13) to be introduced from a front side (11) of the fluidic nozzle into said pocket (3); a form-locking latching connection (8, 18) fixing said nozzle body in said housing, without deformation of said nozzle body and said housing, in an operational position, wherein the form-locking is attained by complementary forms of the nozzle body and the housing; and wherein the form-locking latching connection is accomplished by contact of a projection with a recess along an interface between an inner surface of the pocket and an outer surface of the nozzle body, the projection being formed on one of said inner and said outer surfaces, and the recess being formed on the other of said inner and said outer surfaces. 4. The fluidic nozzle as claimed in claim 3, wherein the latching connection (8, 18) is formed by said recess (10, 16) and said projection (9, 15) engaging in the recess. 5. The fluidic nozzle as claimed in claim 3, wherein the nozzle body (4, 13) is prestressed with respect to a plane of the inlet opening (5) by means of the latching connection (8, 18). 6. The fluidic nozzle as claimed in claim 3, wherein the latching connection (8, 18) constitutes means for unreleasably fixing the nozzle body (4, 13) in the housing (1, 17).
