[0021] FIG. 2: a perspective view of the nut;
[0022] FIG. 3: a first sectional representation of the nut along a line of intersection III-Ill shown in FIG. 1;
[0023] FIG. 4: a second sectional representation of the nut along a line of intersection IV-IV shown in FIG. 3;
[0024] FIG. 5: a third sectional representation of the nut along a line of intersection V-V shown in FIG. 3; and

[0026] FIG. 1 shows a lateral view of a sanitary faucet 2 secured with a nut 1 to a support 3. The sanitary faucet 2 has a faucet housing 18 with a pivotable outlet 19. An outlet opening 20 is embodied at the outlet 19, by means of which the sanitary faucet 2 can dispense liquid to an environment 21. A faucet shaft 22 having a thread 6 of the sanitary faucet 2 is inserted through a mounting opening 23 of the support 3 and secured to the support 3 using the nut 1. To this end, a twist lock 8 of the nut 1 was turned to a release position 10 shown in FIG. 3 and the nut 1 subsequently put on the faucet shaft 22 along its longitudinal axis 24, until a first longitudinal end 25 of the nut 1 abuts on an underside 26 of the support 3. Then the twist lock 8 was adjusted to a locking position 9 shown in FIG. 5 and the nut 1 was subsequently manually tightened against the underside 26 of the support 3.
[0027] FIG. 2 shows a perspective view of the nut 1. The (multiple part) nut 1 or nut assembly comprises a base body 4 and the twist lock 8, which is rotatably secured on the base body 4. The base body 4 is tubular and extends along the longitudinal axis 24 from the first longitudinal end 25 to a second longitudinal end 30. Furthermore, the base body 4 has a first length 11 along the longitudinal axis 27 and the twist lock 8 has a second length 12. In addition, the base body 4 comprises a plurality of threaded lugs 5 in the region of the twist lock 8, at which a female thread 28 of the base body 4 is formed. The threaded lugs 5 extend parallel to the longitudinal axis 24 in a longitudinal direction 27, wherein a protruding end 29 of the threaded lugs 5 is oriented toward the second longitudinal end 30 of the base body 4. The twist lock 8 is located in a release position 10 here, in which, when the nut 1 is put on the faucet shaft 22 of the sanitary faucet 2 shown in FIG. 1, the threaded lugs 5 are outwardly adjustable or bendable by means of the thread 6 formed on the faucet shaft 22. As a result, the nut 1 can be pushed onto the faucet shaft 22 without rotation parallel to the longitudinal axis 24. The base body 4 comprises a handle portion 31, which extends from the twist lock 8 to the second longitudinal end 30 and has a third length 32 parallel to the longitudinal axis 27.
[0028] FIG. 3 shows a first sectional representation of the nut 1 along a line of intersection III-Ill shown in FIG. 1. In particular, in the embodiment variant of the nut 1 shown here it can be seen that the base body 4 has six threaded lugs 5, which are evenly distributed in a circumferential direction 33 of the nut 1. The twist lock 8 is in the release position 10 here, in which free spaces 15 in the radial direction 7 are in accord with the threaded lugs 5. As a result, the threaded lugs 5 are outwardly adjustable in the radial direction 7 in the free spaces 15 of the twist lock 8.
[0029] FIG. 4 shows a second sectional representation of the nut 1 along a line of intersection IV-IV shown in FIG. 3. The free space 15 has a depth 35 starting from an inner surface 34 of the twist lock 8 outwardly in the radial direction 7.
[0030] FIG. 5 shows a third sectional representation of the nut 1 along a line of intersection V-V shown in FIG. 3. In the third sectional representation it can be seen that the base body 4 has three stops 14, which extend outwardly in the radial direction 7. Compared to the release position 10 of the twist lock 8 shown in FIG. 3, the twist lock 8 in FIG. 5 has been adjusted or turned counterclockwise by a rotational angle 13 to a locking position 9 relative to the base body 4, until first stop surfaces 36 of the twist lock 8 contact the stops 14 of the base body 4, so that the twist lock 8 can no longer be rotated counterclockwise relative to the base body 4. In the locking position 9 the free spaces 15 of the twist lock 8 in the radial direction 7 are not (completely) in accord with the threaded lugs 5 of the base body 4. As a result, the threaded lugs are 5 locked, so that said threaded lugs are not adjustable outwardly in the radial direction 7. From the locking position 9, the twist lock 8 can be adjusted relative to the base body 4 clockwise by the rotational angle 13 back to the release position 10 shown in FIG. 3, until second stop surfaces 37 of the twist lock 8 contact the stops 14 of the base body 4, so that the twist lock 8 cannot be rotated further clockwise relative to the base body 4.
[0031] FIG. 6 shows a fourth sectional representation of the nut 1 along a line of intersection VI-VI shown in FIG. 5. It can be seen in FIG. 6 that an external surface 38 of the threaded lugs 5 of the base body 4 directly abuts on the inner surface 34 of the twist lock 8, so that the threaded lugs 5 are not outwardly adjustable in the radial direction 7. As a result, the female thread 28 of the base body 4 cannot slip over the thread 6 of the faucet shaft 22 shown in FIG. 1, but is instead in engagement with the thread 6. As a result, the nut 1 on the faucet shaft 22 can be tightened by one turn about the longitudinal axis 24 shown in FIG. 2. The twist lock 8 is guided on the base body 4 between a first axial stop 16 and a second axial stop 17, so that the twist lock 8 cannot come loose from the base body 4 in an axial direction 40, i.e., parallel to the longitudinal axis 24 of the base body 4 shown in FIG. 2. The axial stops 16, 17 extend outwardly from a circumferential surface 39 of the base body 4 in the radial direction 7. The first axial stop 16 is formed on the first longitudinal end 25 of the base body 4. The second axial stop 17 is embodied such or is so small in the radial direction 7 that the twist lock 8 can be pushed onto the base body 4 in the axial direction 14 to the first axial stop 16 by means of an elastic deformation of the twist lock 8 and/or of the second axial stop 17 from the second longitudinal end 30 of the base body 4 shown in FIG. 2.
[0032] By means of the present invention, sanitary faucets can be secured with minimal effort.
