ABSTRACT:
Apparatus for clamping the hose of a nipple including a clamp of the type having a band with interengageable barb means and apertures spaced from one another for accommodating maintenance of the band in a clamping position around a hose. A tightening device for accommodating assembly and disassembly of the band around a hose is provided, which tightening device includes a rigid housing having apertures engageable with barbs on the band and a rigid member having teeth for engaging in apertures in the band slidably guidably carried by the rigid housing. A manually rotatable gear wheel is pivotally mounted in the fixed housing and includes gear teeth engageable with gear teeth at the rigid bar such that pivotal movement of the gear wheel forces the rigid bar to move in the circumferential direction with respect to the rigid housing. The rigid housing and rigid bar are constructed so as to be guided for movement with respect to one another along a circular arc corresponding in radius to the radius of the band or hose being clamped. The gear wheel is rigidly attached to a manually operable lever.
