Unknown connector type
The connector appears to be an "IDC" Insulation Displacement Contact type. Where the thru-wires are laid into a sharp fork-shape contact and then pressed into it with a separate back-piece. The sharp fork cuts through the wire insulation and makes contact with the wire. A quick check (and several decades of experience) show that the 1x4 configuration exactly as your photo shows is an uncommon type.  You may be searching for a while to find identical replacements.

Those connectors typically are NOT water tight, but they are probably low voltage, so not as important. Note that the PITCH (distance between pins) is CRITICAL. There may be very similar connectors with slightly different pitches but they are NOT interchangeable.  It is critical that you measure the pitch of the pins in order to find compatible connectors.

Your bent tubes may be able to be straightened by careful, gentle heating. Perhaps from a few minutes in an oven set for the lowest temperature or a hair-dryer, etc.
