Abstract: A head armature for a respiratory system includes a cradle and a retention mechanism. The cradle is configured to receive a respiratory mask assembly in a stand-by position. The retention mechanism is configured to detachably connect the respiratory mask assembly with the head armature such that the respiratory mask assembly is movable from the stand-by position to a use position while connected to the head armature and such that the respiratory mask assembly is selectively detachable from the head armature in a stand-alone configuration whereby the respiratory mask assembly is disconnected from the head armature. In the use position, the respiratory mask assembly is configured to provide oxygen to a user. The head armature is configured to be worn on a head of the user such that the cradle is between the respiratory mask assembly and the user's head when the respiratory mask assembly is in the stand-by position.

Abstract: In a spring nut (10) for attachment onto a stud (12), having a substantially oblong seat for the stud (12), the seat having an axial insertion opening (32) for the stud (12) and a holding section for the stud (12), provision is made that the spring nut (10) completely encloses the seat on a front wall (28) opposite the insertion opening (32) and in the peripheral direction.

Abstract: In a fixation clip (10) for at least one line (18), with a frame (12) which defines a receiving space (14, 14a, 14b) for the line (18), into which space the line (18) can be introduced such that the frame (12) encloses the line (18) in circumferential direction, wherein an insertion opening (16, 16a, 16b) for the line (18) is provided at the frame (12), and with at least one swivel arm (22, 22a, 22b) mounted on the frame (12), which can be moved from a holding position, in which the line (18) is fixed in the receiving space (14, 14a, 14b), in a swivel direction (S) into an assembly position in which the line (18) can be introduced through the insertion opening (16, 16a, 16b) into the receiving space (14, 14a, 14b), a web (24) is provided, which with a first end is mounted on the swivel arm (22, 22a, 22b) and with a second end is mounted on the inside of the frame (12), wherein the web (24, 24a, 24b) includes at least one joint (34, 34a, 34b) and is folded in the assembly position.
