## Abstract

A spark plug connector (1) including a connector body (21) formed as an insulator having a spark plug high voltage contact (35) for producing a connection to and with a spark plug (6). The connector body (21) has a connection point (23) for receiving, mounting and/or connection of a spark plug connector (1) extending structural element (22). The structural element (22) is arranged at the junction (23) in such a manner such that the structural element (22) lengthens the connector body (21) on the side remote from the spark plug high voltage contact. The ignition cable (3) is held or guided along the length of the structural element (22) and the material of the structural element has a higher rigidity and strength and/or a lower density with at the same time less material than the material of the connector body (21).

## Claims
