The connecting muff has two ends (6,8) and an inner threaded section (4) for engagement of a threaded bolt. It also has an outer threaded section (3) with a number of threads (13) for anchoring in a wall or similar. The outer threaded section at its end facing the second end (8) of the muff, has at least one cutting edge (11) extending over a few of the threads (13). The outer diameter of the outer threaded section in the area of the cutting edge reduces in the direction of the second end from its nominal diameter to one which is smaller. Between the outer threaded section and the second end of the muff is a cylindrical guide section (10). Connected to the guide section is a conical introduction section (9) extending as far as the second end. |
