ABSTRACT:
The hose clamp for fire hoses on hose couplings comprises a nipple whereon the hose end is pushed. The hose end is pressed on the nipple via a radially resiliently compressible clamping sleeve by means of a clamping element against the outer surface of the nipple. The clamping sleeve comprises a conical outer face and the clamping element a conical inner face cooperating therewith. The clamping element consists of two generally semicylindrical clamping shells which are braced against each other at their peripheral ends by clamping screws which extend approximately tangentially through the wall thickness of the clamping shells. The nipple comprises an encircling annular collar which forms a radial abutment face for the hose end and the clamping sleeve. The conical inner face of each clamping shell adjoins at the end of its large diameter a radially inwardly directed collar which lies axially outside the region of the clamping zone and which engages behind the annular collar of the nipple and through the enlarged wall thickness of which at least one of the clamping screws extends.
