Abstract
A sintered metallic filtering element in the form of a porous metallic tube is provided with a connecting fitting by forming the tube with an internal surface in the form of an internal truncated cone of circular cross section at one end of the tube, the internal truncated cone having a vertex half angle .alpha. greater than zero. The connecting member of the invention includes a truncated cone shaped head of circular external cross section having a vertex half angle .alpha. which is the same as the vertex half angle .alpha. of the internal truncated cone of the tube. The head of the connecting member is disposed inside the porous metallic tube and cooperates with the internal truncated cone. The connecting member also includes a tubular extending member attached to the smaller end of the head, with the tubular extending member extending beyond the porous metallic tube.
