ABSTRACT:
A band retaining unit includes a female retaining body adapted to be mounted securely on a canvas, a male retaining body connected pivotally to the female retaining body, a gripping element disposed slidably on the male retaining body, and a spring element biasing the engagement arms of the gripping element to engage within the gripping notches of the female retaining body, so as to clamp tightly a retaining band between the male retaining body and the female retaining body. The gripping element is provided with a projection which is positioned so that when a rope is passed through the rope holes of the female retaining body and into the depressions of the male retaining body, the projection is obstructed by the rope from moving in the band retaining unit, thereby locking the gripping element on the female retaining body.
