A crossmember 4 rotates freely on the body 2, thus being held between the internal face 5 of the base 3 and the bottom 6 of the head 7 of the spindle 1. The branches 9,9' of a shackle 10 respectively rotate on the lateral bearing journals 8, 8' of the crossmember 4. The support of each branch 9, 9'on the associated bearing journal 8, 8' is provided by a retaining ring 11 with a circular section fully engaged in a throat with a semi-circular section fitted on the periphery of the bearing journal.
