Patent ID: 6857664

Claim:
A mounting stop for axially displaceable male-female couplings to prevent involuntary release of the coupling, comprising a recess arranged to be placed in a first position around a shaft and to be displaceable radially sidewise above said shaft to a second position, and at least one stop lug arranged, in said first position to be applied into a groove and thereby to prevent an axial displacement of said male-female coupling parts towards each other, the recess of the mounting stop having on its one side a diameter corresponding to the diameter of a shaft part over which it is intended to be placed in a first position and wherein the recess of the mounting stop on its other side has a diameter which is less than the diameter of the shaft part over which it is intended to be brought in a second position, the differences in diameters between the recess parts allowing for the mounting stop to automatically return to its said first position.
