Sensing element for determining a physical property of a gas mixture

A sensing element for determining a physical property of a gas mixture, comprising:

• a housing;
• at least one electrical cable;
• a sensor element arranged in the housing and connected to the at least one electrical cable;
• a molded piece made of an elastically deformable material and for sealing the housing, the molded piece enclosing the at least one electrical cable in a gas-tight manner by radial compression;
• and
• a spring element arranged in the molded piece, the spring element being able to be tensioned by the radial compression and in the tensioned state generating a force component that acts on the at least one electrical cable in a radial manner wherein:
• the molded piece includes a blind hole and at least two feed-through holes, each being designed for the at least one electrical cable and arranged on a divider circle that is concentric with respect to the blind hole, and
• the spring element includes a clamping sleeve that is rolled up as a helical spring and inserted into the blind hole.
