Hermetic adjustable hose clamp

A hermetic adjustable hose clamp for clamping two tubular elements having ends positioned one inside another, the clamp comprising a substantially circular strap including a solid nonperforated central portion and two end portions which are wider than said central portion and each being recessed, said circular strap having two turns and adapted to surround said tubular elements in an inserted position, said turns being formed by said central portion and overlapping one another, said strap further including two loops formed by said end portions and extending outwardly from said turns, each loop having two loop portions formed by a recess of each of said end portions and spaced from each other and aligned with one another;

• two solid substantially cylindrical members, said two loops being substantial parallel to each other and each receiving one of said substantially cylindrical members, each cylindrical member having a transversal hole in a center thereof;
• and an adjustable screw extending through each hole for joining said cylindrical members to each other so as to apply radial forces to said turns and to clamp said tubular elements together to thereby prevent any leakage of a medium therefrom.
