Beschreibung
Zusammenfassung:	An elevator (100) having a hole (101h) wherein the sidewalls of the hole (101h) are shaped with a receiving surface (RS) for receiving correspondingly-shaped sidewalls of the end portion (99e) of a pipe (99). Similarly, sidewalls of the end portion (99e) are shaped with an engagement surface (ES) for engagement with correspondingly-shaped sidewalls of the hole (101h). Both the receiving surface (RS3) and the engagement surface (ES3) comprise a first part (ES3a, RS3a) and a second part (ES3b, RS3b) neighbouring the first part (ES3a, RS3a), the first part (ES3a, RS3a) defining a frustoconical shape (p1) having a first conicity, the second part (ES3b, RS3b) defining a shape (p2) having at least partially a second conicity lower than the first conicity.
