Elastic retainer perfected, comprising the performance of a ball, submitted. To the axial expansion of a spring, it is essentially characterized in that it is constituted by a cylindrical tubular body having, at one of its ends, a peripheral projection or flange and a partial closure of its section, obtained by means of a peripheral zigzag bending of, its side wall, while the opposite end of said tubular body has an internal peripheral rim, also obtained by bending at an angle of its side wall; said partial closing of its first end establishing an axial hole through which protrudes the ball of greater diameter, housed inside the tubular body by the opposite end, while the rim of the latter establishes the axial seat of the conical spring of expansion against the ball.
