Filter for fluids

A fluid filter comprising:

• top and bottom housing parts,
• a raw fluid inlet disposed on one of said parts and an outlet disposed on the other of said parts,
• a filter element disposed within and between said housing parts,
• peripheral sealing means positioned between said housing parts for sealing the same when assembled, and
• fastener means for releasably secure said housing parts together,
• wherein said filter element is configured as a bag and said top and bottom housing parts are provided at the circumferential sealing margins thereof with bores, said bores being aligned with one another, and said fastener means consist of catch pins inserted into the bores for removably assembling said parts,
• wherein said aligned bores are configured as elongated holes and at least one said catch pin has a cross pin adapted to be inserted into said elongated holes and at least one of said top and bottom parts has a inclined plane means with a recess, adjacent the bore in said at least one of said top and bottom housing parts for releasable securing said cross pin after being inserted through the aligned bore said catch pin is rotated by a quarter turn to disalign the cross pin with the elongated hole and move the cross pin up the inclined plane means and into the recess to thereby secure said housing parts together, the catch pin being rotatable to an open position to allow separation of the housing parts.
