## Abstract

Disclosed is a closing cap for media-tight sealing of a plug face of a plug-and-socket connector, in particular a round plug-and-socket connector, wherein the closing cap can be detachably fixed to a plug-and-socket connector housing, wherein the closing cap is configured, such that a further closing cap of identical construction can be detachably fixed to the closing cap. The closing caps can be stored, for example stacked one on top of the other, on a plug-and-socket connector housing in a switchgear cabinet. This simplifies storage in that when a closing cap is removed from one connector it may be stored on a closing cap of an adjacent connector.

## Claims

### Claim 1

A closing cap for media-tight sealing of a plug face of a round plug-and-socket connector, wherein the closing cap is adapted to be detachably fixed to a plug-and-socket connector housing, wherein
the closing cap is configured, such that a further closing cap of identical construction can be detachably fixed to the closing cap
the closing cap has the form of two cylinders placed one over the other, which substantially form a locking cylinder and a docking cylinder with a baseplate,
the locking cylinder is adapted to be fixed to a plug-and-socket connector housing and to a docking cylinder of a closing cap of identical construction,
the main axes of symmetry of the locking cylinder and the docking cylinder are aligned with one another,
and an outer diameter of the locking cylinder is greater than an outer diameter of the docking cylinder, and
the locking cylinder is adapted be fixed in accordance with a bayonet principle to a plug connector housing and/or to a closing cap of identical construction.

### Claim 2 (depends on 1)

The closing cap as claimed in claim 1, wherein the closing cap has a seal, which is arranged in a groove provided inside the closing cap.

### Claim 3 (depends on 1)
