Claim Text:
1. An insertion endpiece for connecting a part carrying said endpiece with another part provided with a bore for receiving the endpiece, the endpiece being provided with an outer groove in which there is received a cylindrical ring possessing teeth projecting from its outside surface, the ends of the teeth, in a free state, projecting radially outwardly from the outer groove for engaging the bore having a diameter less than the diameter of a substantially cylindrical envelope defined by the ends of the teeth, wherein the ring is received in the outer groove while being free to turn and to slide, wherein the axial width of the outer groove is greater than the axial width of the ring, wherein when the ring is in abutment against a flank of the outer groove, the teeth are in register with a secondary groove formed in the bottom of the outer groove receiving the ring, into which secondary groove the teeth are capable of penetrating elastically, wherein the ends of the teeth are cut skew so as to bite into the bore at an angle of inclination relative to a generator line of its surface and wherein a first one of the flanks of the groove and the facing end of the ring possess means for putting the ring into rotary abutment in the groove in such a manner that, when the ring is in abutment against said first one of the flanks, the ring is free to turn relative to the endpiece over an angle of less than 360 degrees, and wherein the means for putting the ring into rotary abutment include rotary drive abutments, and the endpiece carries an engagement abutment that is elastically deformable in the engagement direction and that, in the absence of axial force between the ring and the endpiece, maintains the ring away from the first one of the flanks of the outer groove so as to prevent any co-operation between the rotary drive abutments.
