Filter for systems of pipes conveying blood. The housing of the filter comprises two parts 11, 12 each of which comprises a clamping face 19a, 19b. The edge of the membrane 15 is held by clamping between the faces 19a, 19b. The parts of the housing are connected together by a weld 26 which is separated from the membrane by a narrow slit 29. Weld particles, which can be formed during ultrasound welding, are thus prevented from migrating from the weld 26 to the active part of the membrane 15 of the filter. <IMAGE> |
