摘要： A device for locking two concentrically positioned and axially displaceable members against displacement in one direction, characterized by a recess formed in one of said members and opening in the direction of the second member, and by locking elements located in said recess, said recess having a first part with a bottom portion positioned at a greater distance from said second member than the distance corresponding to the size of the locking elements in a direction transversally to the axial direction of said members, and a second part of said recess having a bottom portion decreasing its distance to said second member in the axial direction of said members and from the first mentioned bottom portion to a distance less than the distance corresponding to the size of the locking elements in said direction transversally to the axial direction of the members, whereby the locking elements are free from locking engagement between said elements, when located in said first part of recess and engaging said members for locking the members against displacement in at least one direction, when located in said second part of recess, and by an actuating element for displacing the locking elements between said parts of recess.
