Abstract
Abstract A locking device for locking lines including bands, cables, ropes or the like utilizing a wedge lock principle. The device is made so that once the line to be locked into position is placed in the locking device, the locking member or key cannot be removed. This makes the device suitable for locking all sorts of lines or flexible elongated members because the locking member will not be lost.

Claim 1
Independent Claim
182 words
A clamping assembly for a line or the like, said clamping assembly comprising an outer housing member having an opening therethrough defined by surface portions, a lock member in said opening, said lock member having a wedge end and an opposite end, said opposite end being of larger size than said opening to block passage thereof through said opening, and said wedge end being of size so that it will pass through said opening in a first direction, said lock member being movable to a first position into said opening in said first direction a distance sufficient to permit a line to be held to pass through said opening and past the wedge end with the lock member in said opening before said opposite end stops movement of said lock member in said first direction, and said line being of size to be wedged against a first surface portion by said wedge end when said wedge end is moved in a second opposite direction with said line in place extending through the opening between said first surface portion and said wedge end.
