A cable securing device facilitates secure connection to a cabling end, and employs a retaining cap, a barrel and a cable receiving component. The cable receiving component can include a spacer gland, a fastening ring and a retaining jaw, or a subset thereof, and the elements of the cable receiving component may either be joined together as individual elements or provided as an integrated cartridge.

A grouting device for high-coagulability grouting materialsincludes a grouting pipe, a connector and a self-sealing pipe head, wherein one end of the connector is connected with a grouting pump through the grouting pipe, the other end of the connector is connected with the self-sealing pipe head through the grouting pipe, and the grouting pipe is connected with the connector and the self-sealing pipe head in a fixed and sealed mode. The grouting device is easy to install, features reliable connection between the grouting pipe and the connector and the self-sealing pipe head, and can be reused. Because the inner diameter of the connector is consistent with the inner diameter of the grouting pipe, and a slurry outlet on an end cap of the self-sealing pipe head is a circular slurry outlet, pressure loss in the grouting process is effectively reduced, and the grouting effect is good.

A permanent connector for making a connection point or for connecting objects together. The connector has a body with first and second ends. A male end is connected to the first end and has a neck portion with a groove. The groove has a base and straight sidewalls extending generally perpendicular to the base. A female end is connected to the second end and has an opening defined by interior walls. A recess is formed in the interior walls with a snap ring mounted in the recess. The snap ring is received within the groove when the male end is inserted into the female end resulting in the male end being permanently connected within the female end.

A gripper for a pipe connector includes a body, a first tooth, and a second tooth. The body has a first side, a second side adjacent the first side, a third side adjacent the first side and opposite the second side, and a fourth side adjacent the second side and the third side and opposite the first side. The first tooth extends from the fourth side of the body at a first distance from the first side of the body perpendicular to the first side of the body. The second tooth extends from the fourth side of the body at a second distance from the first side of the body perpendicular to the first side of the body, the second distance less than the first distance.

A double band clamp assembly for use with a no-hub coupling.

A double band clamp assembly for use with a no-hub coupling.

Pipe coupling: a male portion (13) provided with a series of spaced keys (15); a female portion (14) provided with a series of spaced keyways (16) so the keys are a sliding fit; a fastener including a male portion fitting (17) secured to or formed in the male portion (13) and providing at least one internally screw-threaded bore (17b); a female portion socket attached to or formed in the female portion, said female portion socket (18a) including a central aperture (23) shaped to receive a plug (24), both the female portion socket and the plug being radiused to match the radius of the female portion; a securing bolt (27) dimensioned to fit in a corresponding fixing aperture (26) formed in said plug and engage with said bore (17b); wherein when the at least one fastener is assembled the plug is a circumferential clearance fit in the female portion socket.

A connector assembly comprising: a first connector part and a second connector part, each connector part defining a fluid flow passage therethrough configured to together define a fluid flow conduit when the first and second parts are connected together, the connector assembly further comprising an extension part mounted around one of the first and the second connector parts, the extension part arranged to move relative to the connector part around which it is mounted to extend across an interface area between the first connector part and the second connector part and to bridge the first and second connector parts when the first and second connector parts are brought to meet each other to define the fluid conduit.
