Abstract
The invention relates to a film chamber for receiving a test object to be tested for the presence of a leak, including at least two film layers and at least two frame elements, each of which has a sealing surface so that the two frame elements lie against each other in a gas-tight manner in order to hermetically seal the film chamber. Each of the two film layers has at least one retaining profile in a wall region, and each of the two frame elements has at least one retaining groove in the frame element sealing surface in order to receive a retaining profile such that the two film layers are held between the two frame elements substantially by a formfitting connection.
