An assembly includes a first element provided with a snap-fitting bead; and a second element having a snap-fitting lip, capable of passing over the snap-fitting bead so as to allow the second element to be mounted on the first element so that it can rotate freely. The assembly includes structure for allowing the snap-fitting lip to pass over the snap-fitting bead when the assembly is fitted together. By rotating the first element with respect to the second, the structure for allowing the lip to pass over the snap-fitting bead is inoperative for taking the assembly apart.

[ What is claimed is:] [1.] An assembly having a longitudinal axis, the assembly comprising:a first element including a snap-fitting bead, said snap-fitting bead extending in a first plane perpendicular to the longitudinal axis and having at least one opening delimited by a first end forming a ramp portion and a second end extending in said first plane; anda second element including a snap-fitting lip, said snap-fitting lip extending in a second plane perpendicular to the longitudinal axis and having at least one opening delimited by a first end forming a ramp portion and a second end extending in said second plane, said at least one opening of said snap-fitting lip being complementary with said at least one opening of said snap-fitting bead;wherein, when said first element and said second element of the assembly are fitted together, said ramp portion of said at least one opening of said snap-fitting bead engages said ramp portion of said complementary at least one opening of said snap-fitting lip in response to a rotation of said first element with respect to said second element so that said snap-fitting lip passes over said snap-fitting bead, thus allowing said second element to be mounted on said first element irreversibly so that said second element can rotate freely;wherein there is an unblocked gap between said ramp portion of said at least one opening of said snap-fitting bead and said second end of said snap-fitting bead with which said ramp portion defines said at least one opening of said snap-fitting bead; andwherein there is an unblocked gap between said ramp portion of said at least one opening of said snap-fitting lip and said second end of said snap-fitting lip with which said ramp portion defines said at least one opening of said snap-fitting lip.
