Claims: What is claimed as new is:

1. In a rotary cylinder-barrel hydraulic machine having a plate including cavities, piston rods with ball-shaped ends mounted in the cavities, an elastically deformable annular clip having an undulating peripheral configuration and having:

a plurality of arcuately spaced radial loops about said clip each comprising a central portion coacting with a respectively corresponding ball-shaped end to be retained by said clip, an outer portion coacting with axial abutment provided on the plate to retain said loop, and an inner portion interconnecting said loop to adjacent loops and coacting with a retaining member cooperating with the plate, each of said loops coacting with a respective ball-shaped end to retain each of those ends in the corresponding cavities while deforming to compensate for errors in the positioning of the ball-shaped ends.

2. Device as set forth in claim 1, wherein the loop section contacting said ball-shaped piston-rod end is of circular arc configuration.

3. Device as set forth in claim 1, wherein said clip has a contact surface shaped for partially accomodating the curvature of said ball-shaped piston-rod end.
