If I understand you correctly, just put the the vertline class to the the span with the input field. Heres an example:
.vertline {
border-right: 4px solid black;
padding-right: 5px;
display: inline-block;
}
<div>
<button class="hin"></button>
<label>Home</label>
<span class="vertline"><input type="text" placeholder="search videos" name="search"></span>
<span><input type="submit" value="" class="tel"></span>
</div>
