Abstract

A device for a hose fitting having at least one cartridge housing with a first connecting piece or a spray plate with a second connecting piece and a hose, which can be connected at least to the first connecting piece or the second connecting piece, whereby further a clamping sleeve is provided, which clamps an end region of the hose on the outside at least to the first connecting piece or the second connecting piece and with an inward directed collar encompasses a projection of the first connecting piece or of the second connecting piece. A non-metallic, inseparable snap connection is formed with two clamping sleeves toward the cartridge housing and toward the spray plate.

First claim

What is claimed is:

1. A water cartridge housing assembly, comprising:
at least one cartridge housing with a first connecting piece or a spray plate with a second connecting piece and a hose, which is connected at least to the first connecting piece or the second connecting piece;
a clamping sleeve, which clamps an end region of the hose on an outside at least to the first connecting piece or the second connecting piece; and
the clamping sleeve having an inward directed collar that encompasses a projection of the first connecting piece or of the second connecting piece,
wherein press rings are formed to project from a same, level internal surface of the clamping sleeve to press the hose against the first connecting piece or the second connecting piece, and
wherein, in a fully assembled state of the clamping sleeve on the first connecting piece or on the second connecting piece, the radially inward-most extent of the press ring farthest removed from the inward directed collar is substantially axially aligned with a distal end of the first connecting piece or the second connecting piece in a radial direction and projects radially inward to a greater extent than all other press rings projecting from the internal surface of the clamping sleeve.

2. The water cartridge housing assembly according to claim 1 , wherein the collar and the projection form a snap connection.

3. The water cartridge housing assembly according to claim 1 , wherein the clamping sleeve and at least the first connecting piece or the second connecting piece form an inseparable connection.

4. The water cartridge housing assembly according to claim 1 , wherein the inward directed collar is provided with a plurality of slots along a circumference thereof.

5. The water cartridge housing assembly according to claim 1 , wherein a distal end of the hose abuts against a side surface of the projection of the first connecting piece or the second connecting piece.

6. The water cartridge housing assembly according to claim 1 , wherein a water cartridge is provided inside of the at least one cartridge housing.

7. The water cartridge housing assembly according to claim 1 , wherein each of the press rings are separated from one another in an axial direction of the clamping sleeve by portions of the same, level internal surface of the clamping sleeve.

8. A device for a hose fitting comprising:
at least one cartridge housing with a first connecting piece or a spray plate with a second connecting piece;
a hose connected at least to the first connecting piece or the second connecting piece;
a clamping sleeve, which clamps an end region of the hose to an outside of the first connecting piece or the second connecting piece,
wherein the clamping sleeve has an inward directed collar that encompasses a projection of the first connecting piece or a projection of the second connecting piece,
wherein the clamping sleeve has press rings that are formed to project from a same, level internal surface of the clamping sleeve to press the hose against the first connecting piece or the second connecting piece, and
wherein, in a fully assembled state of the clamping sleeve on the first connecting piece or on the second connecting piece, the radially inward-most extent of the press ring farthest removed from the inward directed collar is substantially axially aligned with an opening of the first connecting piece or the second connecting piece in a radial direction and projects radially inward to a greater extent than all other press rings of the clamping ring.

9. The device according to claim 8 , wherein each of the press rings are separated from one another in an axial direction of the clamping sleeve by portions of the same, level internal surface of the clamping sleeve.
