ABSTRACT:
The invention relates to straps which include an elongate strap portion, a housing at one end of the strap and a screw member which is adapted to be positioned in the housing to draw the strap portion through the housing. In particular, the invention relates to straps which are easily drawn to a predetermined tension about an article by means of a screw member having a weakened section between the head and the threaded shank. The weakened section fractures when a predetermined torque on the screw member is reached, preventing overtightening and also indicating that the required tension in the strap portion has been reached. The screw may have two heads, the second head being revealed when the first breaks off, to permit the strap portion to be released. Straps according to the invention may also be used as security seals, if no second head is provided, as then the strap must be broken to be removed.
