Abstract

A protective device ( 5, 5″, 5″, 5′″, 5″″ ) is provided for a hose clip ( 4 ) that connects a hose end ( 2 ) to a hose connection ( 3 ). The protective device includes a protective body ( 8, 8′, 8″, 8′″, 8″″ ) made of a plastic. In the assembled state, the protective body ( 8, 8′, 8″, 8′″, 8″″ ) surrounds the circumference of the hose clip ( 4 ) and accommodates the hose clip ( 4 ) at least in its clamping region via a radially oriented molding ( 32 ), and covers the hose clip ( 4 ) over the width thereof extending in the longitudinal direction of the hose connection ( 3 ). The protective body ( 8, 8′, 8″, 8′″, 8″″ ) has ring segments ( 9, 10 ) that can be connected to one another at their free ends ( 12, 13 ), and the segments are connected moveably to one another at their ends ( 14, 17 ) facing away from the free ends ( 12, 13 ).

First claim

The invention claimed is:

1. A protective device ( 5 ) for a hose clip ( 4 ), the hose clip ( 4 ) having a clamping device ( 7 ) that defines a clamping region of the hose clip ( 4 ) via which a hose end ( 2 ) can be connected to a hose connection ( 3 ), the protective device comprising:
a protective body ( 8 , 8 ′, 8 ″, 8 ′″, 8 ″″) made of a plastic and being assemblable to the hose clip ( 4 ) so that, in an assembled state, the protective body ( 8 ) surrounds the hose clip ( 4 ) around a circumference thereof and accommodates the hose clip ( 4 ) at least in the clamping region thereof via a radially oriented moulding ( 32 ), the moulding covering the hose clip ( 4 ) over a width of the hose clip ( 4 ) extending in a longitudinal direction of the hose connection ( 3 ), the protective body ( 8 , 8 ′, 8 ″, 8 ′″, 8 ″″) including:
a stiff intermediate ring segment ( 11 ) with opposite first and second circumferential ends;
a first flexible section ( 15 ) at the first circumferential end of the stiff intermediate ring segment ( 11 );
a first stiff terminal ring segment ( 9 ) having a first articulated end ( 14 ) movably connected to the first flexible section ( 15 ) and a first free end ( 12 ) opposite the first articulated end ( 14 );
a second flexible section ( 18 ) at the second circumferential end of the stiff intermediate ring segment ( 11 ); and
a second stiff terminal ring segment ( 10 ) having a second articulated end ( 17 ) movably connected to the second flexible section ( 18 ) and a second free end ( 13 ) opposite the second articulated end ( 17 ), wherein
the first free end ( 12 ) of the first stiff ring segment ( 9 ) is connectable to the second free end ( 13 ) of the second stiff ring segment ( 10 ).

2. The protective device of claim 1 , wherein the first free end ( 12 ) of the first stiff ring segment ( 9 ) has a first latching element ( 20 , 21 ) and the second free end ( 13 ) of the second stiff ring element ( 10 ) has a second latching element ( 22 , 23 ), the first and second latching elements ( 20 , 21 , 22 , 23 ) being engageable with one another to form a latch mechanism ( 24 ).

3. The protective device of claim 1 , wherein the protective body ( 8 ′, 8 ″, 8 ′″, 8 ″″) has, at least on a side thereof that is facing away from the hose connection ( 3 ), a kink protection ( 25 , 25 ″, 25 ′″, 25 ″″) formed as an overlapping element to accommodate a portion of the hose ( 6 ).

4. The protective device of claim 3 , wherein the kink protection ( 25 ″″) comprises a cylinder ( 30 ) that is directed away from the protective body ( 8 ″″) and that has radially outward-directed annular ribs ( 31 ).

5. A connection assembly for connecting a hose end ( 2 ) on a hose connection ( 3 ), the connection assembly comprising:
a hose clip ( 4 ) having a clamping device ( 7 ) configured for clamping the hose end ( 2 ) on the hose connection ( 3 ); and
a protective body ( 8 , 8 ′, 8 ″, 8 ′″, 8 ″″) made of a plastic and being assemblable to the hose clip ( 4 ) so that, in an assembled state, the protective body ( 8 ) surrounds the hose clip ( 4 ) around a circumference thereof and accommodates the hose clip ( 4 ) at least in the clamping region thereof via a radially oriented moulding ( 32 ), the moulding covering the hose clip ( 4 ) over a width of the hose clip ( 4 ) extending in a longitudinal direction of the hose connection ( 3 ), the protective body ( 8 , 8 ′, 8 ″, 8 ′″, 8 ″″) including:
a stiff intermediate ring segment ( 11 ) with opposite first and second circumferential ends;
a first flexible section ( 15 ) at the first circumferential end of the stiff intermediate ring segment ( 11 );
a first stiff terminal ring segment ( 9 ) having a first articulated end ( 14 ) movably connected to the first flexible section ( 15 ) and a first free end ( 12 ) opposite the first articulated end ( 14 );
a second flexible section ( 18 ) at the second circumferential end of the stiff intermediate ring segment ( 11 ); and
a second stiff terminal ring segment ( 10 ) having a second articulated end ( 17 ) movably connected to the second flexible section ( 18 ) and a second free end ( 13 ) opposite the second articulated end ( 17 ), wherein
the first free end ( 12 ) of the first stiff ring segment ( 9 ) is connectable to the second free end ( 13 ) of the second stiff ring segment ( 10 ).
