Abstract

A closing device is provided for a container of a respirator with two container shells ( 2, 2 ′) joining each other at front surfaces, with at least one tightening strap ( 4 ), which encloses a part of a container shell outer surface located at right angles to the front surfaces. Two holding elements ( 5, 5 ′) are each provided with a recess ( 6, 6 ′) and are formed at the free ends of the tightening strap ( 4 ). A closing element ( 7 ) is formed in a U-shaped pattern with two legs ( 8 ) and meshes with each recess ( 6, 6 ′) of the holding elements ( 5, 5 ′). The legs ( 8 ) of the closing element ( 7 ) can be pulled out of the recess ( 6, 6 ′) of the holding elements ( 5, 5 ′) to take off the tightening strap ( 4 ).
