Replaceable filter having a filter closure system

A replaceable filter comprising:

• a filter housing with an end face formed as a cylindrical connecting end one-piece unitary with said filter housing;
• a housing lid having a cylindrical counter connecting member matching said cylindrical connecting end;
• a filter closure system that seal-tightly connects by form fit said cylindrical connecting end and said cylindrical counter connecting member when said cylindrical connecting end is inserted or pushed onto said cylindrical counter connecting member in an axial connecting direction and moved by a relative movement, comprising at least one of an insertion movement and a rotation movement, relative to said cylindrical counter connecting member;
• an annular member having a U-shaped cross section, the annular member arranged within said filter housing, said annular member arranged coaxially relative to and radially inwardly of said filter housing at its cylindrical connecting end, said annular member including:
• a base portion having a free edge;
• an annular seal groove formed in a radial outer wall surface of said base portion at said free edge;
• a sealing device as an annular seal arranged in said seal groove;
• a radially inner leg of said U-shaped cross section of said annular member extending axially inwardly from said base portion and terminating at a securing device, the securing device having a plurality of spaced apart springy locking elements, the springy locking elements engaging onto a top surface or a radial outer edge of an end element of a filter insert arranged in said housing;
• and
• a radially outer leg of said U-shaped cross section of said annular member extending axially inwardly from said base portion to an opposing end facing a bottom of the filter housing, the opposing end, the radially outer leg having a terminal edge area that is received against and welded to or adhesively secured seal-tightly onto an interior side of said filter housing such that said annular member and said cylindrical connecting end form boundaries of a receptacle for said cylindrical counter connecting member;
• wherein said sealing device is arranged in said receptacle and connected to said filter housing, said sealing device interacting with said cylindrical counter connecting member;
• wherein said annular member and said cylindrical connecting end of said filter housing delimit said receptacle therebetween;
• wherein said cylindrical counter connecting member is inserted into said receptacle, said cylindrical counter connecting member positioned radially intermediately between said cylindrical connecting end of said filter housing and said annular member;
• wherein a first set of interacting elements is secured on said interior side of said filter housing at said cylindrical connecting end;
• wherein a second set of interacting elements is arranged on said cylindrical counter connecting member;
• wherein said first set of interacting elements engage said second set of interacting elements.
