That part of the mobile tubular element (7) including between the annular row of holes (8) in which the locking balls (9) are housed and the nearest external shoulder (23) of the tubular element (7), which serves to support a return spring (16) is surrounded by a cylindrical bushing (24) whose inside end is provided with a flange (25) which is normally biased against the external shoulder (23) of the mobile tubular element (7), whose other end, which is normally biased against the internal tapered face (6a) of the internal rib (6) in the body (2), is internally beveled so as to provide a divergent face (26), whereby the length of the cylindrical skirt of this bushing (24) slightly exceeds the distance between the aforesaid shoulder (23) and the annular row of holes (8) housing the balls (9).
