One-piece housing of a worm driven hose clamp

Abstract

A one piece housing for a worm driven hose clamp includes a screw and a clamping band. The screw has a head and a shank. The shank is threaded. The housing includes a vaulted housing upper part and a housing lower part. The vaulted housing upper part has an open edge. The vaulted housing upper part receives the shank of the screw and supports the head at the opening edge. The housing lower part receives a first end segment and a second end segment of the clamping band. The first end segment has screw-thread segments. The threaded shank meshes with the screw thread segments. The housing lower part includes a base. The second end segment is fixed to the base. The housing lower part has only one side extension part for supporting the housing against turning during tightening of the screw. The side extension part has an upper wall comprising an upper wall segment, a lower wall segment and an upward-projecting wall. The upper wall segment and the lower wall segment overlap each other. The upward-projecting wall is connected to the base and, by a transition segment, to the upper wall segment. A portion of the transition segment is formed to create a cutout. The lower wall segment extends, at least in part, to an inner side of the upward-projecting wall. The lower wall segment extends, at least in part, into the cutout of the transition segment.
