Abstract
A clamp fitting is disclosed, constituted by a metal band wound on itself, whose ends are respectively provided with complementary hooking means, comprising a hook capable of passing behind a shoulder or ear during the clamping operation. The clamp fitting presents at least one group of two undulations, each in the form of an open loop, projecting radially with respect to the outer periphery of the clamp fitting, the zone of join of at least one undulation to the clamp fitting being constituted by a portion of band of circular section, whose radius is at least equal to twice the thickness of the band and which extends over an arc of at least 90.degree. and preferably close to 150.degree..
Claims13
A clamp comprising:
- a) a metal band wound on itself including an inner end provided with a first lug and an outer end provided with a hook to form a complementary fastening means, the hook adapted to pass over the first lug during the clamping operation;
- and
- b) at least one group of alternating undulations projecting outwardly from the outer periphery of said metal band and forming an M-shaped portion, said group of undulations including a first joining section connecting said group of undulations to said metal band, the first joining section having a radius of at least twice the thickness of said metal band and extending through an arc of at least 90.degree..
A clamp comprising:
- a) a band wound on itself including an inner end and an outer end, said band provided with complementary fastening means on the outer end and proximate the inner end of said metal band, the fastening means adapted to be coupled to each other;
- b) at least one tensioning loop projecting outwardly from said band, said tensioning loop including a group of alternating undulations forming an M-shaped portion;
- and
- c) a first arcuate structure joining said tensioning loop to said band, said first arcuate structure having a radius of at least twice the thickness of said band and extending through an arc of at least 90.degree..
