no further description is necessary mounted to the clamping band near its overlapping ends is a band tightening means housing 30 composed of a driven gear means housing 32 housing the driven gear means 40 and a drive gear means housing 34 housing the drive gear means 50 the housing 34 is mounted perpendicularly to the housing 32 forming an 34 l 34 shape the purpose of which will become apparent later in the description the longitudinal length of the housing 34 can vary depending upon the needs of the user for instance referring to fig7 a when access to the clamp is relatively easy or when space is limited the length l 1 of the housing 34 can be made short relative to the length l 2 of housing 32 thus reducing the amount of material used in making the clamp however as shown in fig7 b the length l 1 of the housing 34 can be made long relative to the length l 2 of housing 32 thus making it easier for a person to access the clamp with a tool contained substantially within the driven gear housing 32 is the driven gear means 40 the driven gear means 40 includes an elongated worm screw 42 rotationally mounted in the housing 32 the screw is operatively engaged with the slits 26 so that the band is constricted or expanded when the screw is rotated located at one end of the screw is a hex head 44 having a driving slot 46 sized for receiving a tool such as a screw driver for rotating the worm screw located at the other end of the screw is a driven gear 47 the.
