Abstract: The invention refers to a clamp for tubular connections in small refrigeration systems of the type which comprises a compressor operatively associated with a refrigeration circuit containing at least one working fluid, said refrigeration system comprising a tubular connecting element, in an elastically deformable material, to be attached around a tubular element that conducts working fluid. The clamp comprises two semi-annular portions having, each one, a first end and a second end, said first ends being coupled to each other and the second end of one of said semi-annular portions being provided with a locking means to be engaged in a lock receiving means provided in the second end of the other semi-annular portion, the coupling between the two first ends being made so as to allow said two semi-annular portions to be displaced between an open position, allowing to place the clamp around the tubular connecting element and a closed position, with the locking means retained in the lock receiving means.

Abstract: A system for closing a suction muffler of a hermetic compressor, the suction muffler including: a hollow base; a cover to be coupled to the hollow base, the parts defined by the hollow base and the cover including respective mutually seatable peripheral flanges, which are shaped to define, jointly, an internal channel extended along at least part of the circumferential extension of the peripheral flanges and which is opened to the opposite external faces of the latter by means of throughbores axially aligned to each other in pairs, each pair of throughbores maintaining a circumferential distance in relation to an adjacent pair of throughbores, the throughbores of each pair and the internal channel being filled with a gasket of injected material, which projects outwardly from the throughbores so as to define an axial lock portion.
