Abstract
Abstract A hose clip which can be tightened without a screw has an elongated band with a first end section which is formed with a closed slot for threading of the second end section therethrough. The end portion of the first end section has a pallet which engages one of a series of external teeth on the second end section to hold the band against expansion when the band surrounds and is tightened around an elastic hose. The end portion of the first end section extends radially outwardly and abuts against a back support which is an integral part of the first end section and is formed by looping the first end section radially outwardly adjacent to its end portion. The provision of the back support on the first end section enhances the versatility of the hose clip by enabling it to properly clamp smaller- or larger-diameter hoses without affecting the ability of the end portion of the first end section to remain in proper engagement with a selected tooth of the second end section. The teeth of the second end section form a row extending in the longitudinal direction of the band.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
165 words
An annular hose clip, comprising an elongated flexible band having an inner side arranged to surround a portion of an elastically deformable component, a first end section and a second end section, said first end section having an end portion, a slot and an outwardly looped intermediate portion integral with said end portion and defining a substantially radially outwardly extending back support in the region of said end portion and said slot, said second end section extending through said slot and having detent means engaged by said end portion and urging the latter against said back support in response to the tendency of the surrounded component to expand the band when the latter is tightly applied therearound, said end portion of said first end section extending substantially radially inwardly toward said detent means and said back support having a substantially radially extending exposed surface abutting against said end portion when the latter engages with and is urged by the detent means against said back support.
Claim 2
Dependent Claim
165 words
An annular hose clip, comprising an elongated flexible band having an inner side arranged to surround a portion of an elastically deformable component, a first end section and a second end section, said first end section having an end portion, a slot and an outwardly looped intermediate portion integral with said end portion and defining a substantially radially outwardly extending back support in the region of said end portion and said slot, said second end section extending through said slot and having detent means engaged by said end portion and urging the latter against said back support in response to the tendency of the surrounded component to expand the band when the latter is tightly applied therearound, said end portion of said first end section extending substantially radially inwardly toward said detent means and said back support having a substantially radially extending exposed surface abutting against said end portion when the latter engages with and is urged by the detent means against said back support.
Claim 3
Dependent Claim
42 words
The hose clip of claim 1, wherein said detent means includes a series of detent elements disposed one behind the other, as considered in the longitudinal direction of said band, one of said detent elements being in engagement with said end portion.
Claim 4
Dependent Claim
35 words
The hose clip of claim 1, wherein said first end section further comprises an elongated tongue which is overlapped by said second end section, said slot being disposed between said tongue and said back support.
Claim 5
Dependent Claim
32 words
The hose clip of claim 3, wherein said tongue is bent out of said slot subsequent to the making of a substantially U-shaped slit in the material of said first end section.
Claim 6
Dependent Claim
27 words
The hose clip of claim 4, wherein said second end section has an elongated groove provided in said inner side and said tongue extends into said groove.
Claim 7
Dependent Claim
27 words
The hose clip of claim 5, wherein said groove is a depression in said inner side and said band has an outwardly extending protuberance opposite said depression.
Claim 8
Dependent Claim
30 words
The hose clip of claim 1, wherein said end portion has a tip which is bent away from said back support, as considered in the circumferential direction of said band.
Claim 9
Dependent Claim
