In-line filter with quick-change coupling and a filter

An in-line filter provided with a transponder and a substantially elongated filter housing in which filtering material is included, the filter housing being provided on a first end with an inflow opening and on a second, opposite end with an outflow opening, while at the inflow opening and the outflow opening fastening means are provided for fastening a supply or discharge tube, respectively,

• wherein the fastening means are quick-change couplings, a respective quick-change coupling having a coupled condition and an uncoupled condition, while in the quick-change coupling a shut-off valve is provided which, in the coupled condition, assumes an open position and thus allows gas to pass and which, in an uncoupled condition, assumes a closed position and thus does not allow gas to pass;
• and
• wherein each quick-change coupling comprises a male part and a female part through which a bore extends, which forms the fluid communication between the supply or discharge tube, respectively, and the inflow opening or outflow opening, respectively, of the filter housing, while, with the male part and the female part in coupled condition, the quick-change coupling is in the coupled condition and with the male part and the female part in uncoupled condition, the quick-change coupling is in the uncoupled condition;
• and
• wherein a screw thread on the male part for connecting the male part to the female part, is provided on a fastening ring rotatably connected to the male part of such that only the fastening ring needs to be turned for fastening the male part in the female part and that therefore the remaining parts of the male part need not be rotated.
