Die hier beschriebene Spannschelle besteht aus einem Klemmband (10), dessen beide Endabschnitte (11, 12) im geschlossenen Zustand der Spannschelle einander überlappen. Auf beiden Bandabschnitten (11, 12) ist jeweils ein Spannhaken (15, 18) angeordnet, und der Spannhaken (15) auf dem inneren Bandabschnitt (11) weist eine dem äußeren Bandabschnitt (12) zugewandte Schrägfläche (31) als Auffahrrampe auf. Erfindungsgemäß weist jeder der Spannhaken (15, 18) mehrere, vorzugsweise drei, vom jeweils anderen Spannhaken abgewandte Vorsprünge (38, 39) auf, die ein sicheres Verkrallen eines beim Schließen der Spannschelle angesetzten Zangenwerkzeugs und damit ein sicheres Schließen gewährleisten.

Provided is a boot band 31 that is capable of preventing the occurrence of buckling in the inner-layer portion of a band body 33. In the boot band 31, by applying a diameter-reducing tightening force on the band body 33 when an engagement pawl 41 of the inner-layer portion 35 of the band body 33 has entered a top-end engagement hole 42 of the outer-layer portion 34 of the band body 33, the top-end engagement hole 42 rides over the engagement pawl 41. Buckling is prevented by providing, at the area of the top-end engagement hole 42 opposite where the engagement pawl 41 enters therein, a guide means 51 that faces the engagement pawl 41.

In order to close and tension a hose clamp, the two end portions (11, 13) of a clamping band (10), which overlap one another, are provided on surfaces that face one another and have toothed areas (20, 22), which are held in reciprocal engagement by a holding device. The toothed area (20) of one end portion (11) is formed on the outer face of a tongue (12), the width of said tongue being less than the full width of the band. The holding device has a raised area (15) that is formed in the other end portion (13) and bears the other toothed area (22) on the inner face thereof. The raised area (15) begins spaced from the free end of the other end portion (13) with an outwardly projecting step (16) that has an opening (18) for the tongue (12) to pass through.

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 (FT), said refrigeration system comprising a tubular connecting element (10), in an elastically deformable material, to be attached around a tubular element (20) that conducts working fluid (FT). The clamp (30) comprises two semi -annular portions (31) having, each one, a first end (32) and a second end (33), said first ends (32) being coupled to each other and the second end (33) of one of said semi-annular portions (31) being provided with a locking means (40) to be engaged in a lock receiving means (50) provided in the second end (33) of the other semi-annular portion (31), the coupling between the two first ends (32) being made so as to allow said two semi -annular portions (31) to be displaced between an open position, allowing to place the clamp (30) around the tubular connecting element (10) and a closed position, with the locking means (40) retained in the lock receiving means (50).
