1. Two parts (1, 2) which can be latched to one another and, in the latched sate, can be rotated with respect to one another, the parts having radially resilient latching hooks, which are arranged in the form of a ring, on one of the two parts (1 or 2) and an annular flank (5), for supporting the latching hooks (3) in the axial direction, on the other part (2 or 1), in which latching connection the latched-in latching hooks (3) are secured by a fixing ring (6), which is aligned concentrically with respect to the arrangement of the latching hooks (3), against undesired release from their latched-in position, and the fixing ring (6) and the body which forms the annular flank (5) are elastically deformable in the radial direction, and in which latching connection, furthermore, the width of an annular gap (8) between the fixing ring (6) and a radial latching-hook abutment surface of the annular flank (5) is smaller than a radial width of the latching hooks (3), wherein the fixing ring (6) and the body which forms the annular flank (5) are each designed as a ring which is fastened in each case, on one of the parts (1 and 2) which is to be connected, via individual webs (7) which are spaced apart over the circumference.
