Abstract: A tightening device is provided for footwear, in particular, for sports footwear of the kind comprising a substantially rigid outer element and a substantially flexible inner element. The tightening device comprises a strap element and the strap element is configured so that—when it is tensioned—it is capable of applying pressure directly both onto the outer element and to the inner element, whereby the pressure is applied more efficiently and uniformly and the user's comfort is thus increased. In addition, the strap element has a substantially continuous surface, which increase the stability of the tightening device and eliminates the risk of an incorrect positioning also in the case of high stresses during sports practices.

Abstract: A single eye clamp adapted to receive a pipe or a pair of telescoped pipes includes a ring body with its end portions being flattened upon one side extending radially outward of the body with the flattened ends in engagement and threaded. An apertured clamp anchor receives the outturned end and a fastener is threaded upon the outturned ends for peripherally contracting the body throughout 360.degree. to secure the ring to the pipe or for securing the pipes together.

Abstract: A saddle or U-bolt clamp is formed from a unitary sheet metal stamping folded to provide hexagonal sleeve formations which receive the legs of the bolt in axially slidable relation. Torque transmitted to the ends of the sleeve formations as the securing nuts are drawn up on the legs of the bolt against the saddle will construct the saddle and U-bolt's bight around the telescoped tubing parts of the exhaust system of vehicles for which such a clamp commonly is used. The heavy duty use for which such clamp is required is permitted even in those critical applications where the transverse profile of the clamp must be substantially reduced or restricted without loss of efficacy and strength of the clamp.

Abstract: A U-bolt clamp assembly for securing together the annular overlap of a pair of telescoped engaging pipes having a U-bolt having a semi-circular bight portion terminating in a pair of legs having threaded ends. A saddle plate assembly includes a saddle plate having a concave seat of semi-circular shape and a pair of spaced keys at the upper ends of the saddle plate seat. The saddle plate assembly is apertured at its ends to receive the U-bolt legs. Opposed keyways upon the interior of the legs interlockingly receive the keys. Fasteners upon the U-bolt ends are tightly drawn into compressive engagement drawing together the U-bolt and saddle plate assembly. The U-bolt bight and the concave seat deform both pipes forming concentric annular channels therein and a bead in the outer pipe nested within the channel of the inner pipe so that the U-bolt and saddle are mechanically interlocked with the outer pipe and the pipes are annularly interlocked, secured and sealed throughout 360.degree..
