Abstract
The elevator guide rail element comprises a guide rail element having a first jointing clamp attached to a lower end of the guide rail element and a second jointing clamp attached to an upper end of the guide rail element. The first and the second jointing clamp forms a plug-in joint between the first and the second jointing clamp and thereby between two consecutive guide rail elements when the first and the second jointing clamp are connected to each other.
