ABSTRACT:
A flow regulator, jet regulator or backflow preventer (11) having at least two components or parts (2, 11), a first one (2) of which can be inserted into a receiving opening (12) of the second part (12). The two parts (2, 11) can be interconnected using a locking arrangement (13, 17). One part is provided with at least one locking cam while the other part (11) is provided with a locking groove which is assigned to the locking cam and is used as a counterpart. One of the parts is provided with a slot (15) or similar recess located at a distance (a) from the outer or inner circumference of the part (2) in the area of the at least one locking groove. The wall section (16) of the part which supports the locking groove or locking cam located on the inner or outer side can be resiliently deflected into and out of the slot in a locking manner due to the resiliency thereof so that a reduced amount of pressure is required to lock the parts (2, 11) together while allowing for comparatively greater tolerances for the snap-in connection. One component can be made of a transparent or semi-transparent material as a filtering sieve or attached sieve (2) while the second is embodied as a jet regulator, flow regulator and/or backflow preventer.
