摘要

The device comprises a tube (3) is fixed externally at its end (30) has the smaller diameter tube (5) introduced into it. A hollow cylindrical piece (2) whose internal wall (20) is truncated on one part has its smallest diameter opening located on the side of the largest tube. The truncated part can be displaced longitudinally with the end part (40) of a collar (4) which is threaded on the smaller tube. The end part of the collar has a cylindrical internal part and truncated external part, and is transversely elastic. It covers internally an elastic sleeve (6) of external diameter corresponding to the internal diameter of the collar and of internal diameter slightly greater than the external diameter of the smaller diameter tube. The collar external truncated part is divided longitudinally into spaced strips (41).
