Please advice Shower control brand name and model?

A valve clip removal tool is specifically designed for these plastic tabs. It’s a thin, hooked metal tool that slides into the gap where the red arrows are pointing. Insert it at the tab location, hook the retention clip, and either push in or pull out (depending on whether the clip locks inward or outward) while gently pulling on the knob. If resistance is high, check for any additional clips or locking points before applying more force.

Alternatively, a precision flathead screwdriver can also work if you don’t have a specialized tool. Using a small flathead, carefully wedge it into the gap near the tab and apply light pressure to release the lock while pulling on the knob. Be careful not to use excessive force. A plastic trim removal tool is another good option, as it provides leverage without risking damage to the surrounding surfaces. If space is tight, a right-angle pick tool can help by reaching into the small opening and disengaging the locking tab with minimal effort.

I’ve been searching but couldn’t find the exact model. The closest match I found is the Delta T17140-SS, but it doesn’t seem to have the same locking mechanism, so your faucet might be from a lesser-known brand or an older model.

Since you've already tried several methods to unlock it without success, I’d suggest directly prying off the temperature control. Some models have it clipped in rather than locked, so it might come off with gentle force.

Thank you very much for your suggestions. Where can I buy this Delta T17140 ? Home Depot?

[TinyTool]

The Delta T17140 trim kit has been discontinued, and it's not available at Home Depot or Lowe’s. You might still find some leftover stock from third-party retailers, but I couldn’t locate any at the major stores. If you're looking for a similar replacement, you may want to check Delta’s Monitor 17 series for an updated model. Also, kindly make sure you have the exact model before purchasing a replacement, so you don’t run into compatibility issues while replacing it.

Thank you, you are saying, I probably need to replace the entire shower control with different model or brand? Any suggestions?

Since the handle isn’t coming off, it’s tough to confirm the exact brand and find the right trim kit. At this point, it might be a good idea to call in a plumber. They have the right tools to safely remove the handle without damaging anything inside. If it turns out to be Delta, you might still have some trim kit options, like the MultiChoice or Monitor 17 series. But if it’s another brand, a plumber can help figure that out and let you know whether you can just swap the trim or if replacing the valve would be the better way to go. Since replacing the valve means opening up the wall, it’s definitely worth getting the right info before making a decision.
