A vacuum system securing device (110) to releasably secure a sealed connection between a first part and a second part of a vacuum system has a shaft (112) having a longitudinal axis and is provided with a plurality of force applying members (116). The shaft (112) is to be attached to the first part of the vacuum system to define a gap between the first part and the force applying members (116), to receive the second part, and is movable relative to the first part to cause the force applying members (116) to narrow the gap to apply a force pressing the second part towards the first part. |
