Patent ID: 7493824

Claim:
A connecting element for the releasable sealed connection of a fluid line system to a pressure transducer for detecting positive and negative pressures of a fluid located in the connecting element comprising: a housing, at least one fluid line connection to the housing, a measuring chamber in the housing which measuring chamber communicates with the fluid line connection, a diaphragm adjacent to the measuring chamber, which diaphragm is tightly connected to the housing for sealing the measuring chamber, and a connecting section on the housing for a repeatedly releasable connection of the connecting element to the pressure transducer, wherein the connecting section has a tubular connection pointing away from the housing and for slipping onto or into a corresponding connecting tube of the pressure transducer, and at least one locking element for the repeatedly releasable connection of the connecting element to the pressure transducer, the tubular connection communicating with the diaphragm and being designed for the airtight connection of the connecting element to the pressure transducer.
