A pipe connector connects first and second pipes slidably engageable with each other, the pipe connector including: a side wall extending between a first end and a second end along a longitudinal axis and defining an interior space, the side wall being adapted to be inserted into a floor hole made in a floor; a floor flange extending laterally and outwardly from the first end of the side wall, the floor flange being adapted to rest on a floor surface when the side wall is inserted into the floor hole; and a guiding assembly secured to the side wall and including at least one resilient retaining finger for receiving the first pipe therebetween, the at least one resilient retaining finger being securable to the first pipe when the second pipe is engaged into the first pipe.

Exemplary embodiments are directed to a seal apparatus for sealing an opening of a structure having a thickness at the opening. The seal apparatus includes a first section disposed at a proximal end, a second section disposed at a distal end, and an intermediate section disposed between the first and second sections. The first section defines a cone-like configuration. An opening extends through the first section, the second section, and the intermediate section.

An electrical box for accommodating at least one duplex electrical outlet including a first side, a second side having a mount opening therein. The electrical box also includes a mounting tube. The mounting tube is mountable to the mount opening. The mounting tube further includes first tubular member having a first length, and a second member fittable within the first tubular member. The second member further includes a tubular main body including a tubular portion fittable within the first tubular member, and a first end including a stop. The first end and stop engage the mount opening in the second side.

A tie for holding electrical wire includes a base and a zip tie. The base has an opening for holding a zip tie fastener therein. The zip tie has a first portion having a first width, and a second portion having a second width lesser than the first width. The opening in the base is sufficient to allow the second portion of the tie to pass therethrough, but too small to allow the first portion of the tie to pass therethrough. The tie also includes a connector on the free end of the first portion sized to receive the second portion of the tie.

The present invention provides a base electrical box, and an end portion. The end portion is added to the base electrical box to substantially complete the electrical box. The electrical box also includes at least one intermediate portion that is added to complete the electrical box. The at least one intermediate portion is placed between the base electric box and the end portion.

An apparatus may be used for isolation of a wall or a surface between internal and external environments. The apparatus may comprise an enclosure housing a metal plate and configured for sealing and attaching to the wall, and any metal plate herein may be having at least first, second, and third openings for passing pipe, cable, or gas through the wall. The apparatus may further comprise sealing nuts installed in the first, and second openings for passing a cable or wires while sealing the first and second openings; and a sealing nipple installed in the third opening and operative to pass gas via a pipe between the internal and the external environments while sealing the third opening. The metal plate may comprise holes and may be attached to the enclosure using multiple threaded screws and nuts via the holes.

A drain hose (1) includes a drain hose body (10) and a hard member (20). The hard member (20) includes a notch (22) and hooks (21). The drain hose body (10) includes a protruding portion (14) provided to a part, of an outer periphery of the drain hose body (10), to which the hard member (20) is attached. The protruding portion (14) protrudes to be positioned in the notch (22), and, when force is applied to the drain hose body (10) in a direction to pull the drain hose body (10) from a through hole (P1), depresses edge portions (22a) of the notch (22) in a direction to expand the hard member (20) in diameter.

A sleeve fastening system fastened to a joist pierced with a hole and receiving two pipes and including a cylinder fitted into the hole of which each end receives a pipe, wherein the wall of the cylinder has cut into it at least one tunnel, a flange, each tunnel having openings that emerge on either side of the flange that has a bearing face bearing against the joist and a free face, and for each tunnel, a holding system having a link, a shoe and a locking system, the link being housed in the tunnel with the shoe blocked in a first opening on the side of the free face and wherein the link exits via a second opening on the side of the bearing face and wherein the locking system attaches.
