摘要:
A kit for connecting a toilet pan waste outlet to a waste pipe is described. The kit comprises a connector, the connector including a sleeve portion adapted for connection to the outlet, wherein the sleeve portion is configured to form an axially extending contact surface with the outlet and a fastener, wherein the fastener is configured to apply a retaining force to the sleeve tending to retain the sleeve on the outlet.

In a strap-band type connecting device (1), a strap band (3) has an array of teeth (8), each of which forms a bridged brace (10) between the neighbouring slits (8a) to make a helical thread (9a) engage with the bridged brace (10) when a rod screw (9) is brought at the helical thread (9a) into engagement with the slits (8a) within a housing (4). The bridged brace (10) is curvedly deformed to provide a width-reduced groove (10a) in its lengthwise direction (P) so as to form a cross piece segment (11, 13), a geometrical moment of inertia of which increases along a circumferential direction (R) of the strap band (3) with a sufficient rigidity provided to resist against a bending force from the helical thread (9a) upon rotationally operating the rod screw (9).

A hose clamp includes a band and a worm drive mechanism. The band has a set of slots located between a first and second circumferential end of the band. The worm drive mechanism is connected to the band and causes radial contraction of the band to tighten the band. The worm drive mechanism includes a screw that engages the set of slots for radial contraction of the band. A clamping-pressure-restoring construction is provided in order to maintain a seal between the hose clamp and an underlying hose during use of the hose clamp and when the underlying hose experiences size expansion and contraction due to, for example, temperature fluctuations.

摘要:
A fastening device comprising a band; a housing secured to one end of the band; a bridging member secured below the housing; a drive screw located in the housing; a series of spaced engagement means formed on or in the band and extending from its free end towards the housing; teeth for engagement by the drive screw being formed in the band adjacent the housing; and a connection member attached to the housing and having a hook - like formation to engage one of the engagement means formed in the band, whereby the free end of the band lies inwardly of that part of the band extending to the housing.
