In the FIG. 3B is a detail in section along a line BB in FIG. 3A in which the first connector body 2, the second connector body 3 and the retaining ring 4, in the given order from inside to outside, are shown arranged one inside the other. The first connection body 2 has a circumferential recess 27 for receiving a first clamping ring, not shown, for connection to the diving suit (not shown). An open to the outside, circumferential groove 19 serves to receive a ring seal, not shown, for sealing against the inner wall of the second connector body 3. This has to attach the glove a circumferential groove 22 for receiving a second clamping ring, not shown, which for clamping attachment of Glove (not shown) is used. An intermediate space 24 is provided for receiving a sealing ring disk, not shown, between the first connection body 2 and the second connection body 3. On the outside of the second connection body 3 revolving, a ramp-shaped locking lug 21 is arranged on which the locking ring 4 engages with a circumferential on the inside locking groove 25 when it is pushed to the stop on the second connector body 3. The stopper forms a shoulder 23 on the second connection body 3, on which a shoulder 26 of the securing ring 4 comes to rest. The ramp-shaped locking lug 21 is shaped such that a latching in a Sliding the locking ring 4 counteracts a lower resistance, as a release of the locking connection in a removal of the locking ring. 4

The attachment of the second connector body 3 to the first connector body 2 is also limited by a stop, since the shoulder 23 comes to rest on the second connector body 3 at a shoulder 20 of the first connector body 2. The shoulder 20 of the first connector body 2 has a crown-shaped edge, behind which engage the coupling closures 6 with the pivotally mounted clamping hook to prevent separation of the connecting device 1. Nevertheless, it is possible to open the coupling closures 6 during operation, since a sufficiently large self-locking force counteracts a separation between the first and second connection bodies 2, 3. The circlip 4 is held on the basis of its latching connection in the axial direction of the second connection body 3, but can be rotated with open coupling closures 6 in the circumferential direction, whereby the equipment held on the equipment carrier 5 can be advantageously adjusted during operation. A deliberate separation of the first and second connection body 2, 3 from each other is facilitated by the elastically compressed sealing ring in the groove 19, which acting on the conical inner surface of the second connection body 3 restoring force has a first connection body 2 of the second connection body 3 separating force component. As a result, the counteracting by self-locking of the separation resistance decreases so slowly that the coupling closures 6 can be briefly opened to rotate the locking ring 4, but a desired separation is still supported.

The FIGS. 4A and 4B show the locking ring 4 as a single part in two side views, with the mounted equipment carrier 5, but without the locking carrier closure 17. The equipment carrier 5 is positively connected to the retaining ring 4.

The equipment carrier 5 will be described below with reference to FIG FIG. 5 in conjunction with the FIGS. 4A and 4B described in more detail.

The FIG. 5 shows the equipment carrier 5 in different views. The device carrier 5 preferably has a fastening groove 7 which is open on one side and which is designed with an undercut, which can also be referred to as a dovetail groove or piping groove. The locking ring 4 has a form-fitting engaging in the mounting groove 7 rail 18 (see FIG. 4A ), wherein the rail 18 dovetailed or kederförmige formations which engage in the undercut of the mounting groove 7. The fastening groove 7 preferably has a stop 9 for the rail 18, which means that the fastening groove 7 is guided guided in the circumferential direction of the locking ring 4 on the rail 18, so that a positive connection in the radial direction is formed until the stop 9 in the circumferential direction is reached. The release of the device carrier 5 with the mounting groove 7 of the locking ring 4 with the rail 18 takes place in the reverse direction. The device carrier 5 further comprises the holder 16 for the carrier closure 17 (see FIG. 2 ) on the retaining ring 4. By means of the carrier closure 17 designed as a tension lock, the device carrier 5 can be clamped on the securing ring 4 or against the rail 18.

The device carrier 5 has in the illustrated embodiment, a hinge-like device receptacle 8 for attaching the equipment.
