Check valve element for a check valve assembly and corresponding check valve assembly

A check valve element for a check valve assembly in a fluid-conducting installation, comprising:

• a valve body resiliently-elastically mounted in the check valve element, formed of sheet metal, having a sealing face;
• a holding ring substantially surrounding the valve body in at least one position;
• helical spring arms, resiliently-elastically connected to the holding ring and the valve body, the valve body being repositionable in a parallel manner in an axial direction of at least one of the valve body and the holding ring, the spring arms formed as one piece with and materially integral to the valve body and the holding ring;
• and
• a latching body configured to fasten the check valve element in a latching manner in the fluid-conducting installation of the check valve assembly, the latching body formed as one piece with and materially integral to the holding ring by a curved transition region transitioning the latching body to the holding ring, the latching body extending along the axial direction in an opposing direction facing away from the valve body and having at least two latching protrusions resiliently-elastically repositionable in a radial direction, each latching protrusion separated in the circumferential direction by a gap in the latching body, the latching body being peripherally open in the opposing direction facing away from the holding ring.
