Abstract
The present disclosure relates to guillotine clamp including a U-bolt mounted on a saddle member. The U-bolt has a concave portion that opposes a corresponding concave portion of the saddle member. At least one curved shim is positioned between the concave portions of the U-bolt and the saddle member to provide both sealing and clamping of a lap joint.

A clamp comprising:
- a saddle member having a concave saddle portion;
- a U-bolt mounted on the saddle member, the U-bolt having a concave portion oriented opposed to the saddle member concave saddle portion;
- and
- at least one shim positioned between the U-bolt and the saddle member, the shim being made of metal and forming substantially a full cylinder at least when the saddle member and the U-bolt are drawn completely together.

A clamp comprising:
- a saddle member having a concave saddle portion;
- a U-bolt mounted on the saddle member, the U-bolt having a concave portion oriented opposed to the saddle member concave saddle portion;
- a first curved shim secured to the saddle member concave saddle portion, the first curved shim being made of metal;
- a second curved shim secured to the U-bolt concave portion, the second shim being made of metal, and the first curved shim having a concave side opposed to a concave side of the second curved shim;
- and
- wherein the first curved shim is secured to the saddle member by a snap-fit connection.
