## Abstract

A plug connector is provided which has a base body and a slide element, wherein the base body has a plug side and a connection side, wherein the plug connector forms a plug axis which extends from the plug side to the connection side through plug the connector, wherein the slide element surrounds the base body and is arranged on the same to be movable along the plug axis. The connector additionally has a securing element, wherein the securing element is arranged between the slide element and the connection side of the plug connector, and wherein the securing element is arranged on the base body to be movable between an open position and a locked position.

## Claims

### Claim 1

A plug connector that comprises a base body and a sliding element, wherein
the base body comprises a plugging side and a connecting side, the plugging side being configured to interface with a mating plug connector, and the connecting side being configured to receive an electrical cable;
the plug connector forms a plugging axis that extends from the plugging side to the connecting side through the plug connector;
the sliding element is arranged on said base body in such a manner that said sliding element is able to move along the plugging axis;
the plug connector comprises a securing element, wherein the securing element is arranged between the sliding element and the connecting side of the plug connector;
the securing element is arranged to move on the base body between an open position, in which the sliding element is able to move along the plugging axis in a direction toward the connecting side, and a locked position, in which the sliding element is blocked by the securing element from moving along the plugging axis in the direction toward the connecting side; and
the securing element is configured to lie within an inner peripheral edge of the sliding element when the securing element is in the open position such that the sliding element is able to move past the securing element when moving in the direction toward the connecting side.

### Claim 2 (depends on 1)

The plug connector as claimed in claim 1, wherein the securing element is arranged between the sliding element and a cable gland of the plug connector.

### Claim 3 (depends on 1)

The plug connector as claimed in claim 1, wherein the securing element is arranged in a rotatable manner on the plug connector.

### Claim 4 (depends on 3)

The plug connector as claimed in claim 3, wherein the securing element is arranged on the plug connector in such a manner that said securing element may rotate about the plugging axis.

### Claim 5 (depends on 1)

The plug connector as claimed in claim 1, wherein the securing element is configured in an annular manner and surrounds the base body.

### Claim 6 (depends on 5)

The plug connector as claimed in claim 5, wherein the securing element comprises at least one blocking region wherein the blocking region extends radially from the plugging axis away from the securing element.

### Claim 7 (depends on 6)

The plug connector as claimed in claim 6, wherein
the at least one blocking region in the open position releases the sliding element to enable the sliding element to move; and
the at least one blocking region in the locked position blocks the movement of the sliding element.

### Claim 8 (depends on 6)

The plug connector as claimed in claim 6, wherein the securing element comprises two blocking regions.

### Claim 9 (depends on 8)

The plug connector as claimed in claim 8, wherein the blocking regions are arranged on two opposite-lying circle segments of the securing element.

### Claim 10 (depends on 8)

The plug connector as claimed in claim 8, wherein the securing element comprises four blocking regions that are arranged uniformly over a periphery of the securing element.
