An axial locking device having two separable members which can be locked together and unlocked by relative axial movement of the two members in one direction. A slider is incorporated in one of the members and is movable relative to the member against a spring when the two members are moved axially relative to one another in one direction. The slider is displaced in one angular direction by interengagement of mutually engageable teeth on the one member and on the slider each time the slider is moved axially. This angular displacement of the slider locks the two members together when they are first pushed axially together against the force exerted by the spring on the slider and then unlocks the two members when they are subsequently pushed axially together against the spring force to permit one handed and/or speedy operation of the locking device.
A releaseable axial locking device comprising two separable members adapted to be locked together and unlocked by relative axial movement of either of said two separable members in one direction, a slider juxtaposed one of said two separable members, said slider being movable axially relative to said one of said two separable members, resilient means interposed said slider and said one of said two separable members such that when the two members are moved axially relative to one another in said one direction said slider engages the other of said two separable members, and means for displacing said slider in an angular direction as it is moved axially against said resilient means so that the angular displacement of said slider which occurs when said two separable members are moved relative to each other in said one direction results in said two separable members being locked relative to one another and subsequent angular displacement of said slider which occurs when the two locked members are again moved relatively to one another in said one direction results in said members being unlocked and thereby axially separable in a direction opposite to said one direction.
