## Abstract

A fixable electric plug connection and a process for fixing an electric plug connection includes two housings which are fitted into one another and which carry corresponding socket and plug contacts. One of the two housings is provided with a surrounding groove which can be locked with a surrounding ridge, for example, in the interior of a stop bolt in order to fix the housing. This provides a space-saving arrangement of the plug connection. The ridge, which is required for the locking of the plug connection, exists in any event as a result of the machining tool operation such that the locking is implemented with simple and low-cost measures.

## Claims

### Claim 1

An electric plug connection for use in a vehicle, comprising:
a socket housing having socket contacts contained therein;
a plug housing having plug contacts contained therein, said socket contacts and plug contacts each being connected with electric conducting wires and being mated with one another when said socket housing and plug housing are fitted to one another; and
a one-piece elongated component having only a single through-opening having at lest one projection, one of said socket and plug housings being shaped so as to be insertable into one end of said through-opening, wherein an outer contour of said one housing substantially corresponds to the size of said through-opening and wherein said one housing includes a surrounding groove which can be locked in said through-opening via said at least one projection.

### Claim 2 (depends on 1)

An electric plug connection according to claim 1, wherein the at least one projection arranged in the through-opening is constructed as a surrounding ridge.

### Claim 3 (depends on 2)

An electric plug connection according to claim 2, wherein the surrounding ridge is produced at a given depth (t) of the through-opening, by forming the through-opening in the elongated component using two-sided machining via machining tools having head surfaces that are each provided with a bevel so that the surrounding ridge is formed at the level of a tool junction plane (W) of the machining tools.

### Claim 4 (depends on 1)

An electric plug connection according to claim 1, wherein the through-opening is longer than the first housing.

### Claim 5 (depends on 1)

An electric plug connection according to claim 1, wherein the elongated component used as a fastening element.
