Abstract: A spring bridge (40), for a spring bridge breathing bag plate system (80) of a closed-circuit respirator (100), includes a spring bridge carrier (42) for the arrangement of at least one spring element (82) of a spring bridge breathing bag plate system (80) and at least one fastening element (44) for holding the spring bridge (40) at the closed-circuit respirator (100). The at least one fastening element (44) is a rotating element and/or a sliding element for the rotatable and/or sliding movement of the spring bridge carrier (42) at and relative to the closed-circuit respirator (100). A spring bridge breathing bag plate system (80) is provided for a closed-circuit respirator (100) as well as for a closed-circuit respirator (100).

Abstract: A breathing tube (1), for a respirator (2), includes a flexible tube body (3) with a tube axis (4), with a first tube end (5) and with a second tube end (6). A molding (7) is formed at the first tube end (5). The molding (7) extends at least partially along the tube axis (4) away from the first tube end (5) of the tube body (3). A respirator (2) may be provided, including the breathing tube (1), a breathing unit (14) and a breathing air supply device (15). A breathing tube port (16) is formed at each of the breathing unit (14) and at the breathing air supply device (15) for connecting the breathing tube (1). A mounting device (17) is formed at at least one breathing tube port (16) for mounting the molding (7) of the breathing tube (1).
